Due to Spark, writing big data applications has never been easier…at least until they stop being easy! At Lightbend we’ve helped our customers out of a number of hidden Spark pitfalls. Some crop up often; the ever-persistent OutOfMemoryError, the confusing NoSuchMethodError, shuffle and partition management, etc. Others occur less frequently; an obscure configuration affecting SQL broadcasts, struggles with speculating, a failing stream recovery due to RDD joins, S3 file reading leading to hangs, etc. All are intriguing! In this session we will provide insights into their origins and show how you can avoid making the same mistakes. Whether you are a seasoned Spark developer or a novice, you should learn some new tips and tricks that could save you hours or even days of debugging.

Elasticsearch provides native integration with Apache Spark through ES-Hadoop. However, especially during development, it is at best cumbersome to have Elasticsearch running in a separate machine/instance. Leveraging Spark Cluster with Elasticsearch Inside it is possible to run an embedded instance of Elasticsearch in the driver node of a Spark Cluster. This opens up new opportunities to develop cutting-edge applications. One such application is Dataset Search. Oscar will give a demo of a Dataset Search Engine built on Spark Cluster with Elasticsearch Inside. Motivation is that once Elasticsearch is running on Spark it becomes possible and interesting to have the Elasticsearch in-memory instance join an (existing) Elasticsearch cluster. And this in turn enables indexing of Datasets that are processed as part of Data Pipelines running on Spark. Dataset Search and Data Management are R&D topics that should be of interest to Spark Summit East attendees who are looking for a way to organize their Data Lake and make it searchable.

If you are running Apache Spark in cloud environments, Object Stores —such as Amazon S3 or Azure WASB— are a core part of your system. What you can’t do is treat them like “just another filesystem” —do that and things will, eventually, go horribly wrong. This talk looks at the object stores in the cloud infrastructures, including underlying architectures., compares them to what a “real filesystem” is expected to do and shows how to use object stores efficiently and safely as sources of and destinations of data. It goes into depth on recent “S3a” work, showing how including improvements in performance, security, functionality and measurement —and demonstrating how to use make best use of it from a spark application. If you are planning to deploy Spark in cloud, or doing so today: this is information you need to understand. The performance of you code and integrity of your data depends on it.

Many initiatives for running applications inside containers have been scoped to run on a single host. Using Docker containers for large-scale production environments poses interesting challenges, especially when deploying distributed Big Data applications like Apache Spark. Some of these challenges include container lifecycle management, smart scheduling for optimal resource utilization, network configuration and security, and performance. At BlueData, we’re “all in” on Docker containers – with a specific focus on Spark applications. We’ve learned first-hand how to address these challenges for Fortune 500 enterprises and government organizations that want to deploy Big Data workloads using Docker. In this session, you’ll learn about networking Docker containers across multiple hosts securely. We’ll discuss ways to achieve high availability across distributed Big Data applications and hosts in your data center. And since we’re talking about very large volumes of data, performance is a key factor. So we’ll discuss some of the storage options we explored and implemented at BlueData to achieve near bare-metal I/O performance for Spark using Docker. We’ll share our lessons learned as well as some tips and tricks on how to Dockerize your Big Data applications in a reliable, scalable, and high-performance environment.

Realtime analytics over large datasets has become an increasing wide-spread demand, over the past several years, Hadoop ecosystem has been continuously evolving, even complex queries over large datasets can be realized in an interactive fashion with distributed processing framework like Apache Spark, new paradigm of efficient storage were introduced as well to facilitate data processing framework, such as Apache Parquet, ORC provide fast scan over columnar data format, and Apache Hbase offers fast ingest and millisecond scale random access. In this talk, we will outline Apache Carbondata, a new addition to open source Hadoop ecosystem which is an indexed columnar file format aimed for bridging the gap to fully enable real-time analytics abilities. It has been deeply integrated with Spark SQL and enables dramatic acceleration of query processing by leveraging efficient encoding/compression and effective predicate push down through Carbondata’s multi-level index technique.

In this talk, we will discuss several advantages of the Spark RDD API for developing custom applications when compared to pure SQL-like interfaces such as Hive. In particular, we will describe how to control data distribution, avoid data skew, and implement application specific optimizations in order to build performant and reliable data pipelines. In order to illustrate these ideas, we will share our experiences redesigning a large-scale, complex (100+ stage) language model training pipeline for Spark that was originally built in Hive. The final Spark based pipeline is modular, readable, and more maintainable when compared to previous set of HQL queries. In addition to the qualitative improvements, we also observed a significant reduction in both resource usage and data landing time. Finally, we will also describe Spark optimizations that we implemented for this workload that can be applied toward batch workloads in general.

Many data scientists are already making heavy usage of the Jupyter ecosystem for analyzing data using interactive notebooks. Apache Toree (incubating) is a Jupyter kernel designed to act as a gateway to Spark by enabling users Spark from standard Jupyter notebooks. This allows users to easily integrate Spark into their existing Jupyter deployments, This allows users to easily move between languages and contexts without needing to switch to a different set of tools. Apache Toree is designed expressly for interactive work. It supports interpreters in Scala, Python, and R. In this talk, I will cover the design of Toree, how it interacts with the Jupyter ecosystem and various ways in which users can extend the functionality of Apache Toree via a powerful plugin system.
