26 likes•11,549 views
This document discusses running Sqoop jobs on Apache Spark for faster data ingestion into Hadoop. The authors describe how Sqoop jobs can be executed as Spark jobs by leveraging Spark's faster execution engine compared to MapReduce. They demonstrate running a Sqoop job to ingest data from MySQL to HDFS using Spark and show it is faster than using MapReduce. Some challenges encountered are managing dependencies and job submission, but overall it allows leveraging Sqoop's connectors within Spark's distributed processing framework. Next steps include exploring alternative job submission methods in Spark and adding transformation capabilities to Sqoop connectors.

Sqoop
Apache Sqoop efficiently transfers bulk data between Apache Hadoop and structured datastores such as relational databases. Sqoop helps offload certain tasks (such as ETL processing) from the EDW to Hadoop for efficient execution at a much lower cost. Sqoop can also be used to extract data from Hadoop and export it into external structured datastores. Sqoop works with relational databases such as Teradata, Netezza, Oracle, MySQL, Postgres, and HSQLDB

Event-Driven Messaging and Actions using Apache Flink and Apache NiFi
At Comcast, our team has been architecting a customer experience platform which is able to react to near-real-time events and interactions and deliver appropriate and timely communications to customers. By combining the low latency capabilities of Apache Flink and the dataflow capabilities of Apache NiFi we are able to process events at high volume to trigger, enrich, filter, and act/communicate to enhance customer experiences. Apache Flink and Apache NiFi complement each other with their strengths in event streaming and correlation, state management, command-and-control, parallelism, development methodology, and interoperability with surrounding technologies. We will trace our journey from starting with Apache NiFi over three years ago and our more recent introduction of Apache Flink into our platform stack to handle more complex scenarios. In this presentation we will compare and contrast which business and technical use cases are best suited to which platform and explore different ways to integrate the two platforms into a single solution.

Transactions and Concurrency Control Patterns
Transactions and Concurrency Control Patterns by Vlad Mihalcea
Transactions and Concurrency Control are very of paramount importance when it comes to enterprise systems data integrity. However, this topic is very tough since you have to understand the inner workings of the database system, its concurrency control design choices (e.g. 2PL, MVCC), transaction isolation levels and locking schemes.
In this presentation, I’m going to explain what data anomalies can happen depending on the transaction isolation level, with references to Oracle, SQL Server, PostgreSQL, and MySQL.
I will also demonstrate that database transactions are not enough, especially for multi-request web flows. For this reason, I’m going to present multiple application-level transaction patterns based on both optimistic and pessimistic locking mechanisms.
Last, I’m going to talk about Concurrency Control strategies used in the Hibernate second-level caching mechanism, which can boost performance without compromising strong consistency.

ORC improvement in Apache Spark 2.3
Apache Spark 2.3, released on February 2018, is the fourth release in 2.x line and has a lot of new improvements. One of the notable improvements is ORC support. Apache Spark 2.3 adds a native ORC file format implementation by using the latest Apache ORC 1.4.1. Users can switch between “native” and “hive” ORC file formats. Hive ORC file format is the existing one until Spark 2.2.
In this talk, I'll talk about three key changes. First of all, performance. New native ORC implementation is faster 2x - 11x times on 10TB TPCDS benchmark. Vectorized query execution over ORC files improves Spark ORC query execution greatly. Especially, ORC filter pushdown can be faster than Parquet due to in-file indexes. Second, as a part of native ORC support, Spark 2.3 can convert the Hive ORC tables into Spark ORC data sources automatically. This solves several existing ORC issues and Spark 2.4 will enable it by default. Last, but not least, Spark 2.3 officially supports structural streaming over ORC data sources. You can create a streaming dataset over ORC files.

Writing Apache Spark and Apache Flink Applications Using Apache Bahir
Big Data is all about being to access and process data in various formats, and from various sources. Apache Bahir provides extensions to distributed analytic platforms providing them access to different data sources. In this talk we will introduce you to Apache Bahir and its various connectors that are available for Apache Spark and Apache Flink. We will also go over the details of how to build, test and deploy an Spark Application using the MQTT data source for the new Apache Spark 2.0 Structure Streaming functionality.
Getting started with Apache Spark
Spark is a fast and general processing engine compatible with Hadoop data. It can run in Hadoop clusters through YARN or Spark's standalone mode, and it can process data in HDFS, HBase, Cassandra, Hive, and any Hadoop InputFormat. It is designed to perform both batch processing (similar to MapReduce) and new workloads like streaming, interactive queries, and machine learning.
Introduction to Apache Spark
Apache Spark is a In Memory Data Processing Solution that can work with existing data source like HDFS and can make use of your existing computation infrastructure like YARN/Mesos etc. This talk will cover a basic introduction of Apache Spark with its various components like MLib, Shark, GrpahX and with few examples.

Introduction to Big Data Analytics using Apache Spark on HDInsights on Azure (SaaS) and/or HDP on Azure(PaaS)
This workshop will provide an introduction to Big Data Analytics using Apache Spark using the HDInsights on Azure (SaaS) and/or HDP deployment on Azure(PaaS) . There will be a short lecture that includes an introduction to Spark, the Spark components.
Spark is a unified framework for big data analytics. Spark provides one integrated API for use by developers, data scientists, and analysts to perform diverse tasks that would have previously required separate processing engines such as batch analytics, stream processing and statistical modeling. Spark supports a wide range of popular languages including Python, R, Scala, SQL, and Java. Spark can read from diverse data sources and scale to thousands of nodes.
The lecture will be followed by demo . There will be a short lecture on Hadoop and how Spark and Hadoop interact and compliment each other. You will learn how to move data into HDFS using Spark APIs, create Hive table, explore the data with Spark and SQL, transform the data and then issue some SQL queries. We will be using Scala and/or PySpark for labs.
Ingesting hdfs intosolrusingsparktrimmed
Apache Solr on Hadoop is enabling organizations to collect, process and search larger, more varied data. Apache Spark is is making a large impact across the industry, changing the way we think about batch processing and replacing MapReduce in many cases. But how can production users easily migrate ingestion of HDFS data into Solr from MapReduce to Spark? How can they update and delete existing documents in Solr at scale? And how can they easily build flexible data ingestion pipelines? Cloudera Search Software Engineer Wolfgang Hoschek will present an architecture and solution to this problem. How was Apache Solr, Spark, Crunch, and Morphlines integrated to allow for scalable and flexible ingestion of HDFS data into Solr? What are the solved problems and what's still to come? Join us for an exciting discussion on this new technology.

FPGA-Based Acceleration Architecture for Spark SQL Qi Xie and Quanfu Wang
In this session we will present a Configurable FPGA-Based Spark SQL Acceleration Architecture. It is target to leverage FPGA highly parallel computing capability to accelerate Spark SQL Query and for FPGA’s higher power efficiency than CPU we can lower the power consumption at the same time. The Architecture consists of SQL query decomposition algorithms, fine-grained FPGA based Engine Units which perform basic computation of sub string, arithmetic and logic operations. Using SQL query decomposition algorithm, we are able to decompose a complex SQL query into basic operations and according to their patterns each is fed into an Engine Unit. SQL Engine Units are highly configurable and can be chained together to perform complex Spark SQL queries, finally one SQL query is transformed into a Hardware Pipeline. We will present the performance benchmark results comparing the queries with FGPA-Based Spark SQL Acceleration Architecture on XEON E5 and FPGA to the ones with Spark SQL Query on XEON E5 with 10X ~ 100X improvement and we will demonstrate one SQL query workload from a real customer.

Apache Spark Structured Streaming Helps Smart Manufacturing with Xiaochang Wu
This presentation introduces how we design and implement a real-time processing platform using latest Spark Structured Streaming framework to intelligently transform the production lines in the manufacturing industry. In the traditional production line there are a variety of isolated structured, semi-structured and unstructured data, such as sensor data, machine screen output, log output, database records etc. There are two main data scenarios: 1) Picture and video data with low frequency but a large amount; 2) Continuous data with high frequency. They are not a large amount of data per unit. However the total amount of them is very large, such as vibration data used to detect the quality of the equipment. These data have the characteristics of streaming data: real-time, volatile, burst, disorder and infinity. Making effective real-time decisions to retrieve values from these data is critical to smart manufacturing. The latest Spark Structured Streaming framework greatly lowers the bar for building highly scalable and fault-tolerant streaming applications. Thanks to the Spark we are able to build a low-latency, high-throughput and reliable operation system involving data acquisition, transmission, analysis and storage. The actual user case proved that the system meets the needs of real-time decision-making. The system greatly enhance the production process of predictive fault repair and production line material tracking efficiency, and can reduce about half of the labor force for the production lines.
Improving Traffic Prediction Using Weather Data with Ramya Raghavendra
As common sense would suggest, weather has a definite impact on traffic. But how much? And under what circumstances? Can we improve traffic (congestion) prediction given weather data? Predictive traffic is envisioned to significantly impact how driver’s plan their day by alerting users before they travel, find the best times to travel, and over time, learn from new IoT data such as road conditions, incidents, etc. This talk will cover the traffic prediction work conducted jointly by IBM and the traffic data provider. As a part of this work, we conducted a case study over five large metropolitans in the US, 2.58 billion traffic records and 262 million weather records, to quantify the boost in accuracy of traffic prediction using weather data. We will provide an overview of our lambda architecture with Apache Spark being used to build prediction models with weather and traffic data, and Spark Streaming used to score the model and provide real-time traffic predictions. This talk will also cover a suite of extensions to Spark to analyze geospatial and temporal patterns in traffic and weather data, as well as the suite of machine learning algorithms that were used with Spark framework. Initial results of this work were presented at the National Association of Broadcasters meeting in Las Vegas in April 2017, and there is work to scale the system to provide predictions in over a 100 cities. Audience will learn about our experience scaling using Spark in offline and streaming mode, building statistical and deep-learning pipelines with Spark, and techniques to work with geospatial and time-series data.
A Tale of Two Graph Frameworks on Spark: GraphFrames and Tinkerpop OLAP Artem...
Graph is on the rise and it’s time to start learning about scalable graph analytics! In this session we will go over two Spark-based Graph Analytics frameworks: Tinkerpop and GraphFrames. While both frameworks can express very similar traversals, they have different performance characteristics and APIs. In this Deep-Dive by example presentation, we will demonstrate some common traversals and explain how, at a Spark level, each traversal is actually computed under the hood! Learn both the fluent Gremlin API as well as the powerful GraphFrame Motif api as we show examples of both simultaneously. No need to be familiar with Graphs or Spark for this presentation as we’ll be explaining everything from the ground up!
No More Cumbersomeness: Automatic Predictive Modeling on Apache Spark Marcin ...
Building accurate machine learning models has been an art of data scientists, i.e., algorithm selection, hyper parameter tuning, feature selection and so on. Recently, challenges to breakthrough this “black-arts” have got started. In cooperation with our partner, NEC Laboratories America, we have developed a Spark-based automatic predictive modeling system. The system automatically searches the best algorithm, parameters and features without any manual work. In this talk, we will share how the automation system is designed to exploit attractive advantages of Spark. The evaluation with real open data demonstrates that our system can explore hundreds of predictive models and discovers the most accurate ones in minutes on a Ultra High Density Server, which employs 272 CPU cores, 2TB memory and 17TB SSD in 3U chassis. We will also share open challenges to learn such a massive amount of models on Spark, particularly from reliability and stability standpoints. This talk will cover the presentation already shown on Spark Summit SF’17 (#SFds5) but from more technical perspective.
Apache Spark and Tensorflow as a Service with Jim Dowling
In Sweden, from the Rise ICE Data Center at www.hops.site, we are providing to reseachers both Spark-as-a-Service and, more recently, Tensorflow-as-a-Service as part of the Hops platform. In this talk, we examine the different ways in which Tensorflow can be included in Spark workflows, from batch to streaming to structured streaming applications. We will analyse the different frameworks for integrating Spark with Tensorflow, from Tensorframes to TensorflowOnSpark to Databrick’s Deep Learning Pipelines. We introduce the different programming models supported and highlight the importance of cluster support for managing different versions of python libraries on behalf of users. We will also present cluster management support for sharing GPUs, including Mesos and YARN (in Hops Hadoop). Finally, we will perform a live demonstration of training and inference for a TensorflowOnSpark application written on Jupyter that can read data from either HDFS or Kafka, transform the data in Spark, and train a deep neural network on Tensorflow. We will show how to debug the application using both Spark UI and Tensorboard, and how to examine logs and monitor training.

MMLSpark: Lessons from Building a SparkML-Compatible Machine Learning Library...
With the rapid growth of available datasets, it is imperative to have good tools for extracting insight from big data. The Spark ML library has excellent support for performing at-scale data processing and machine learning experiments, but more often than not, Data Scientists find themselves struggling with issues such as: low level data manipulation, lack of support for image processing, text analytics and deep learning, as well as the inability to use Spark alongside other popular machine learning libraries. To address these pain points, Microsoft recently released The Microsoft Machine Learning Library for Apache Spark (MMLSpark), an open-source machine learning library built on top of SparkML that seeks to simplify the data science process and integrate SparkML Pipelines with deep learning and computer vision libraries such as the Microsoft Cognitive Toolkit (CNTK) and OpenCV. With MMLSpark, Data Scientists can build models with 1/10th of the code through Pipeline objects that compose seamlessly with other parts of the SparkML ecosystem. In this session, we explore some of the main lessons learned from building MMLSpark. Join us if you would like to know how to extend Pipelines to ensure seamless integration with SparkML, how to auto-generate Python and R wrappers from Scala Transformers and Estimators, how to integrate and use previously non-distributed libraries in a distributed manner and how to efficiently deploy a Spark library across multiple platforms.

Hiding Apache Spark Complexity for Fast Prototyping of Big Data Applications—...
In many cases, Big Data becomes just another buzzword because of the lack of tools that can support both the technological requirements for developing and deploying of the projects and/or the fluency of communication between the different profiles of people involved in the projects.
In this talk, we will present Moriarty, a set of tools for fast prototyping of Big Data applications that can be deployed in an Apache Spark environment. These tools support the creation of Big Data workflows using the already existing functional blocks or supporting the creation of new functional blocks. The created workflow can then be deployed in a Spark infrastructure and used through a REST API.
For better understanding of Moriarty, the prototyping process and the way it hides the Spark environment to the Big Data users and developers, we will present it together with a couple of examples based on a Industry 4.0 success cases and other on a logistic success case.
How Nielsen Utilized Databricks for Large-Scale Research and Development with...
Large-scale testing of new data products or enhancements to existing products in a research and development environment can be a technical challenge for data scientists. In some cases, tools available to data scientists lack production-level capacity, whereas other tools do not provide the algorithms needed to run the methodology. At Nielsen, the Databricks platform provided a solution to both of these challenges. This breakout session will cover a specific Nielsen business case where two methodology enhancements were developed and tested at large-scale using the Databricks platform. Development and large-scale testing of these enhancements would not have been possible using standard database tools.
Spline: Apache Spark Lineage not Only for the Banking Industry with Marek Nov...
Data lineage tracking is one of the significant problems that financial institutions face when using modern big data tools. This presentation describes Spline – a data lineage tracking and visualization tool for Apache Spark. Spline captures and stores lineage information from internal Spark execution plans and visualizes it in a user-friendly manner.
Goal Based Data Production with Sim Simeonov
Since the invention of SQL and relational databases, data production has been about specifying how data is transformed through queries. While Apache Spark can certainly be used as a general distributed query engine, the power and granularity of Spark’s APIs enables a revolutionary increase in data engineering productivity: goal-based data production. Goal-based data production concerns itself with specifying WHAT the desired result is, leaving the details of HOW the result is achieved to a smart data warehouse running on top of Spark. That not only substantially increases productivity, but also significantly expands the audience that can work directly with Spark: from developers and data scientists to technical business users. With specific data and architecture patterns spanning the range from ETL to machine learning data prep and with live demos, this session will demonstrate how Spark users can gain the benefits of goal-based data production.
Preventing Revenue Leakage and Monitoring Distributed Systems with Machine Le...
Have you imagined a simple machine learning solution able to prevent revenue leakage and monitor your distributed application? To answer this question, we offer a practical and a simple machine learning solution to create an intelligent monitoring application based on simple data analysis using Apache Spark MLlib. Our application uses linear regression models to make predictions and check if the platform is experiencing any operational problems that can impact in revenue losses. The application monitor distributed systems and provides notifications stating the problem detected, that way users can operate quickly to avoid serious problems which directly impact the company’s revenue and reduce the time for action. We will present an architecture for not only a monitoring system, but also an active actor for our outages recoveries. At the end of the presentation you will have access to our training program source code and you will be able to adapt and implement in your company. This solution already helped to prevent about US$3mi in losses last year.
Getting Ready to Use Redis with Apache Spark with Dvir Volk
Getting Ready to use Redis with Apache Spark is a technical tutorial designed to address integrating Redis with an Apache Spark deployment to increase the performance of serving complex decision models. To set the context for the session, we start with a quick introduction to Redis and the capabilities Redis provides. We cover the basic data types provided by Redis and cover the module system. Using an ad serving use-case, we look at how Redis can improve the performance and reduce the cost of using complex ML-models in production. Attendees will be guided through the key steps of setting up and integrating Redis with Spark, including how to train a model using Spark then load and serve it using Redis, as well as how to work with the Spark Redis module. The capabilities of the Redis Machine Learning Module (redis-ml) will be discussed focusing primarily on decision trees and regression (linear and logistic) with code examples to demonstrate how to use these feature. At the end of the session, developers should feel confident building a prototype/proof-of-concept application using Redis and Spark. Attendees will understand how Redis complements Spark and how to use Redis to serve complex, ML-models with high performance.
Deduplication and Author-Disambiguation of Streaming Records via Supervised M...
Here we present a general supervised framework for record deduplication and author-disambiguation via Spark. This work differentiates itself by – Application of Databricks and AWS makes this a scalable implementation. Compute resources are comparably lower than traditional legacy technology using big boxes 24/7. Scalability is crucial as Elsevier’s Scopus data, the biggest scientific abstract repository, covers roughly 250 million authorships from 70 million abstracts covering a few hundred years. – We create a fingerprint for each content by deep learning and/or word2vec algorithms to expedite pairwise similarity calculation. These encoders substantially reduce compute time while maintaining semantic similarity (unlike traditional TFIDF or predefined taxonomies). We will briefly discuss how to optimize word2vec training with high parallelization. Moreover, we show how these encoders can be used to derive a standard representation for all our entities namely such as documents, authors, users, journals, etc. This standard representation can simplify the recommendation problem into a pairwise similarity search and hence it can offer a basic recommender for cross-product applications where we may not have a dedicate recommender engine designed. – Traditional author-disambiguation or record deduplication algorithms are batch-processing with small to no training data. However, we have roughly 25 million authorships that are manually curated or corrected upon user feedback. Hence, it is crucial to maintain historical profiles and hence we have developed a machine learning implementation to deal with data streams and process them in mini batches or one document at a time. We will discuss how to measure the accuracy of such a system, how to tune it and how to process the raw data of pairwise similarity function into final clusters. Lessons learned from this talk can help all sort of companies where they want to integrate their data or deduplicate their user/customer/product databases.
MatFast: In-Memory Distributed Matrix Computation Processing and Optimization...
The use of large-scale machine learning and data mining methods is becoming ubiquitous in many application domains ranging from business intelligence and bioinformatics to self-driving cars. These methods heavily rely on matrix computations, and it is hence critical to make these computations scalable and efficient. These matrix computations are often complex and involve multiple steps that need to be optimized and sequenced properly for efficient execution. This work presents new efficient and scalable matrix processing and optimization techniques based on Spark. The proposed techniques estimate the sparsity of intermediate matrix-computation results and optimize communication costs. An evaluation plan generator for complex matrix computations is introduced as well as a distributed plan optimizer that exploits dynamic cost-based analysis and rule-based heuristics The result of a matrix operation will often serve as an input to another matrix operation, thus defining the matrix data dependencies within a matrix program. The matrix query plan generator produces query execution plans that minimize memory usage and communication overhead by partitioning the matrix based on the data dependencies in the execution plan. We implemented the proposed matrix techniques inside the Spark SQL, and optimize the matrix execution plan based on Spark SQL Catalyst. We conduct case studies on a series of ML models and matrix computations with special features on different datasets. These are PageRank, GNMF, BFGS, sparse matrix chain multiplications, and a biological data analysis. The open-source library ScaLAPACK and the array-based database SciDB are used for performance evaluation. Our experiments are performed on six real-world datasets are: social network data ( e.g., soc-pokec, cit-Patents, LiveJournal), Twitter2010, Netflix recommendation data, and 1000 Genomes Project sample. Experiments demonstrate that our proposed techniques achieve up to an order-of-magnitude performance.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Sqoop on Spark for Data Ingestion-(Veena Basavaraj and Vinoth Chandar, Uber)
- 1. SQOOP on SPARK for Data Ingestion Veena Basavaraj & Vinoth Chandar @Uber
- 2. Currently @Uber on streaming systems. @Cloudera on Ingestion for Hadoop. @Linkedin on front-end service infra. 2 Currently @ Uber focussed on building a real time pipeline for ingestion to Hadoop. @linkedin lead on Voldemort. In the past, worked on log based replication, HPC and stream processing.
- 3. Agenda • Sqoop for Data Ingestion • Why Sqoop on Spark? • Sqoop Jobs on Spark • Insights & Next Steps 3
- 5. Data Ingestion • Data Ingestion needs evolved – Non SQL like data sources – Messaging Systems as data sources – Multi-stage pipeline 5
- 6. Sqoop Now • Generic data Transfer Service –FROM ANY source –TO ANY target 6 MYSQL KAFKA HDFS MONGO FTP HDFS FROM TO KAFKA MEMSQL
- 7. Sqoop How? • Connectors represent Pluggable Data Sources • Connectors are configurable •LINK configs •JOB configs 7
- 8. Sqoop Connector API 8 Source Targetpartition() **No Transform (T) stage yet! extract() load()
- 9. Agenda • Sqoop for Data Ingestion • Why Sqoop on Spark? • Sqoop Jobs on Spark • Insights & Next Steps 9
- 10. It turns out… • MapReduce is slow! • We need Connector APIs to support (T) transformations, not just EL • Good news! - Execution Engine is also pluggable 10
- 11. Why Apache Spark ? • Why not ? ETL expressed as Spark jobs • Faster than MapReduce • Growing Community embracing Apache Spark 11
- 12. Why Not Use Spark Data Sources? 12 Sure we can ! but …
- 13. Why Not Spark DataSources ? • Recent addition for data sources! • Run MR Sqoop jobs on Spark with simple config change • Leverage incremental EL & job management within Sqoop
- 14. Agenda • Sqoop for Data Ingestion • Why Sqoop on Spark? • Sqoop Jobs on Spark • Insights & Next Steps 14
- 15. Sqoop on Spark •Creating a Job •Job Submission •Job Execution 15
- 16. Sqoop Job API • Create Sqoop Job –Create FROM and TO job configs –Create JOB associating FROM and TO configs • SparkContext holds Sqoop Jobs • Invoke SqoopSparkJob.execute(conf, context) 16
- 17. Spark Job Submission • We explored a few options.! – Invoke Spark in process within the Sqoop Server to execute the job – Use Remote Spark Context used by Hive on Spark to submit – Sqoop Job as a driver for the Spark submit command 17
- 18. Spark Job Submission • Build a “uber.jar” with the driver and all the sqoop dependencies • Programmatically using Spark Yarn Client ( non public) or directly via command line submit the driver program to yarn client/ • bin/spark-submit —class org.apache.sqoop.spark.SqoopJDBCHDFSJobDriver --master yarn /path/to/uber.jar —confDir /path/to/sqoop/server/conf/ — jdbcString jdbc://myhost:3306/test —u uber —p hadoop —outputDir hdfs:// path/to/output —numE 4 —numL 4 18
- 19. Spark Job Execution 19 MySQL partitionRDD extractRDD .map() .map() loadRDD.collect()
- 20. Spark Job Execution SqoopSparkJob.execute(…) List<Partition> sp = getPartitions(request,numMappers); JavaRDD<Partition> partitionRDD = sc.parallelize(sp, sp.size()); 20 1 2 3 JavaRDD<List<IntermediateDataFormat<?>>> extractRDD = partitionRDD.map(new SqoopExtractFunction(request)); extractRDD.map(new SqoopLoadFunction(request)).collect();
- 21. Spark Job Execution 21 MySQL Compute Partitions Extract from MySQL .map() .mapPartition() Load into HDFS .repartition() Repartition to limit files on HDFS
- 22. Agenda • Sqoop for Data Ingestion • Why Sqoop on Spark? • Sqoop Jobs on Spark • Insights & Next Steps 22
- 23. Micro Benchmark: MySQL to HDFS 23 Table w/ 300K records, numExtractors = numLoaders
- 24. Table w/ 2.8M records, numExtractors = numLoaders good partitioning!! Micro Benchmark: MySQL to HDFS 24
- 25. What was Easy? • NO changes to the Connector API required. • Inbuilt support for Standalone and Yarn Cluster mode for quick end-end testing and faster iteration • Scheduling Spark sqoop jobs via Oozie 25
- 26. What was not Easy? • No clean public Spark Job Submit API. Using Yarn UI for Job status and health. • Bunch of Sqoop core classes such as IDF had to be made serializable • Managing Hadoop and spark dependencies together in Sqoop caused some pain 26
- 27. Next Steps! • Explore alternative ways for Spark Sqoop Job Submission with Spark 1.4 additions • Connector Filter API (filter, data masking) • SQOOP-1532 – https://github.com/vybs/sqoop-on-spark 27
- 28. Sqoop Connector ETL 28 Source Targetpartition() **With Transform (T) stage! extract() Transform() load()
- 29. Questions! • Thanks to the Folks @Cloudera and @Uber ! • You can reach us @vybs, @byte_array 29
