HBaseCon 2013: Integration of Apache Hive and HBaseCloudera, Inc.
This document discusses integrating Apache Hive with HBase. It describes how Hive can be used to query HBase tables via a storage handler. Key features covered include using HBase as a data source or sink for Hive, mapping Hive schemas and types to HBase schemas, pushing filters down to HBase, and bulk loading data. The future of Hive and HBase integration could include improvements to schema mapping, filter pushdown support, and leveraging new HBase typing APIs.
Comparing Hive with HBase is like comparing Google with Facebook - although they compete over the same turf (our private information), they don’t provide the same functionality. But things can get confusing for the Big Data beginner when trying to understand what Hive and HBase do and when to use each one of them. We're going to clear it up.
HBase is a column-oriented NoSQL database built on HDFS that is designed for high throughput and large datasets. It is based on BigTable and uses HDFS for storage. Data can be accessed quickly via random reads/writes or processed in batches with MapReduce. HBase has a flexible data model with dynamic columns and is well-suited for applications needing big data storage and access.
HBase is a distributed, column-oriented database that runs on top of Hadoop and HDFS, providing Bigtable-like capabilities for massive tables of structured and unstructured data.

Apache Hive is a data warehouse software built on top of Hadoop that allows users to query data stored in various databases and file systems using an SQL-like interface. It provides a way to summarize, query, and analyze large datasets stored in Hadoop distributed file system (HDFS). Hive gives SQL capabilities to analyze data without needing MapReduce programming. Users can build a data warehouse by creating Hive tables, loading data files into HDFS, and then querying and analyzing the data using HiveQL, which Hive then converts into MapReduce jobs.
Hadoop is an open-source framework for distributed storage and processing of large datasets across clusters of commodity hardware. It addresses problems with traditional systems like data growth, network/server failures, and high costs by allowing data to be stored in a distributed manner and processed in parallel. Hadoop has two main components - the Hadoop Distributed File System (HDFS) which provides high-throughput access to application data across servers, and the MapReduce programming model which processes large amounts of data in parallel by splitting work into map and reduce tasks.
HBase 2.0 is the next stable major release for Apache HBase scheduled for early 2017. It is the biggest and most exciting milestone release from the Apache community after 1.0. HBase-2.0 contains a large number of features that is long time in the development, some of which include rewritten region assignment, perf improvements (RPC, rewritten write pipeline, etc), async clients, C++ client, offheaping memstore and other buffers, Spark integration, shading of dependencies as well as a lot of other fixes and stability improvements. We will go into technical details on some of the most important improvements in the release, as well as what are the implications for the users in terms of API and upgrade paths. Existing users of HBase/Phoenix as well as operators managing HBase clusters will benefit the most where they can learn about the new release and the long list of features. We will also briefly cover earlier 1.x release lines and compatibility and upgrade paths for existing users and conclude by giving an outlook on the next level of initiatives for the project.

The presentation argues Hadoop provides an effective solution for certain data warehouse workloads while maintaining flexibility, ease of scaling, and cost effectiveness.
This document summarizes Facebook's use cases and architecture for integrating Apache Hive and HBase. It discusses loading data from Hive into HBase tables using INSERT statements, querying HBase tables from Hive using SELECT statements, and maintaining low latency access to dimension tables stored in HBase while performing analytics on fact data stored in Hive. The architecture involves writing a storage handler and SerDe to map between the two systems and executing Hive queries by generating MapReduce jobs that read from or write to HBase.
Hive is a data warehousing infrastructure based on Hadoop. Hadoop provides massive scale out and fault tolerance capabilities for data storage and processing (using the map-reduce programming paradigm) on commodity hardware.
Hive is designed to enable easy data summarization, ad-hoc querying and analysis of large volumes of data. It provides a simple query language called Hive QL, which is based on SQL and which enables users familiar with SQL to do ad-hoc querying, summarization and data analysis easily. At the same time, Hive QL also allows traditional map/reduce programmers to be able to plug in their custom mappers and reducers to do more sophisticated analysis that may not be supported by the built-in capabilities of the language.
Hive was initially developed by Facebook to manage large amounts of data stored in HDFS. It uses a SQL-like query language called HiveQL to analyze structured and semi-structured data. Hive compiles HiveQL queries into MapReduce jobs that are executed on a Hadoop cluster. It provides mechanisms for partitioning, bucketing, and sorting data to optimize query performance.
HBase Read High Availability Using Timeline-Consistent Region ReplicasHBaseCon
Speakers: Enis Soztutar and Devaraj Das (Hortonworks)
HBase has ACID semantics within a row that make it a perfect candidate for a lot of real-time serving workloads. However, single homing a region to a server implies some periods of unavailability for the regions after a server crash. Although the mean time to recovery has improved a lot recently, for some use cases, it is still preferable to do possibly stale reads while the region is recovering. In this talk, you will get an overview of our design and implementation of region replicas in HBase, which provide timeline-consistent reads even when the primary region is unavailable or busy.
Jesse Anderson (Smoking Hand)
This early-morning session offers an overview of what HBase is, how it works, its API, and considerations for using HBase as part of a Big Data solution. It will be helpful for people who are new to HBase, and also serve as a refresher for those who may need one.
This document discusses the HiveServer2 project which aims to improve Hive by adding support for sessions, concurrency, ODBC/JDBC, authentication and authorization.

HBaseCon 2015: Analyzing HBase Data with Apache HiveHBaseCon
This document summarizes new features for analyzing HBase data with Apache Hive, including the ability to query HBase snapshots, generate HFiles for bulk uploads to HBase, support for composite and timestamp keys, and additional improvements and future work. It provides an overview of Hive and its integration with HBase, describes the new features in detail, and indicates which releases the features will be included in.
The document proposes using MapReduce jobs to perform scans over HBase snapshots. Snapshots provide immutable data from HBase tables. The MapReduce jobs would bypass region servers and scan snapshot files directly for improved performance. An initial implementation called TableSnapshotInputFormat is described which restores snapshot data and runs scans in parallel across map tasks. The implementation addresses security and performance aspects. An API for client-side scanning of snapshots is also proposed to allow snapshot scans outside of MapReduce.

The document discusses improving Hive metadata performance by using HBase as the backend storage instead of a relational database. It describes storing Hive metadata in HBase tables to provide faster access and greater scalability than when using a relational database. The system caches metadata in memory and uses transactions to manage concurrent access to the cached and stored metadata. Experimental results showed significant latency improvements over using a relational database backend.
Structured Streaming in Apache Spark 2.0 introduces a continuous data flow programming model. It processes live data streams using a streaming query that is expressed similarly to batch queries on static data. The streaming query continuously appends incoming data to an unbounded table and performs incremental aggregations. This allows for exactly-once processing semantics without users needing to handle micro-batching or fault tolerance. Structured Streaming queries can be written using the Spark SQL DataFrame/Dataset API and output to sinks like files, databases, and dashboards. It is still experimental but provides an alternative to the micro-batch model of earlier Spark Streaming.

As supporting evidence, both high-level application architecture and internal details will be discussed. This is an interactive talk: bring your questions and your use-cases!
HBase is a NoSQL database that stores data in HDFS in a distributed, scalable, reliable way for big data. It is column-oriented and optimized for random read/write access to big data in real-time. HBase is not a relational database and relies on HDFS. Common use cases include flexible schemas, high read/write rates, and real-time analytics. Apache Phoenix provides a SQL interface for HBase, allowing SQL queries, joins, and familiar constructs to manage data in HBase tables.
Hortonworks Technical Workshop: HBase and Apache Phoenix Hortonworks
This document provides an overview of Apache HBase and Apache Phoenix. It discusses how HBase is a scalable, non-relational database that can store large volumes of data across commodity servers. Phoenix provides a SQL interface for HBase, allowing users to interact with HBase data using familiar SQL queries and functions. The document outlines new features in Phoenix for HDP 2.2, including improved support for secondary indexes and basic window functions.
Hive is a data warehouse infrastructure tool used to process large datasets in Hadoop. It allows users to query data using SQL-like queries. Hive resides on HDFS and uses MapReduce to process queries in parallel. It includes a metastore to store metadata about tables and partitions. When a query is executed, Hive's execution engine compiles it into a MapReduce job which is run on a Hadoop cluster. Hive is better suited for large datasets and queries compared to traditional RDBMS which are optimized for transactions.
Business intelligence analyzes data to provide actionable information for decision making. Big data is a $50 billion market by 2017, referring to technologies that capture, store, manage and analyze large variable data collections. Hadoop is an open source framework for distributed storage and processing of large data sets on commodity hardware, enabling businesses to gain insight from massive amounts of structured and unstructured data. It involves components like HDFS for data storage, MapReduce for processing, and others for accessing, storing, integrating, and managing data.
Sept 17 2013 - THUG - HBase a Technical IntroductionAdam Muise
HBase Technical Introduction. This deck includes a description of memory design, write path, read path, some operational tidbits, SQL on HBase (Phoenix and Hive), as well as HOYA (HBase on YARN).
This document provides an overview of Hive, including:
- What Hive is and how it enables SQL-like querying of data stored in HDFS folders
- The key components of Hive's architecture like the metastore, optimizer, and executor
- How Hive queries are compiled and executed using frameworks like MapReduce, Tez, and Spark
- A comparison of Hive to traditional RDBMS systems and how they differ
- Steps for getting started with Hive including loading sample data and creating Hive projects
In Hive, tables and databases are created first and then data is loaded into these tables.
Hive as data warehouse designed for managing and querying only structured data that is stored in tables.
While dealing with structured data, Map Reduce doesn't have optimization and usability features like UDFs but Hive framework does.
This document discusses leveraging Apache HBase as a non-relational datastore in Apache Spark batch and streaming applications. It outlines integration patterns for reading from and writing to HBase using Spark, provides examples of API usage, and discusses future work including using HBase edits as a streaming source.
The document discusses new features in Apache Hive 3 including the Data Analytics Studio, connectors to other data systems like Druid and Kafka, and SQL enhancements such as materialized views, constraints and defaults, and query result caching. It provides examples of how these new capabilities can optimize workloads, improve query performance, and enable more flexible data integration and analysis.
The document discusses how Hadoop can be used for interactive and real-time data analysis. It notes that the amount of digital data is growing exponentially and will reach 40 zettabytes by 2020. Traditional data systems are struggling to manage this new data. Hadoop provides a solution by tying together inexpensive servers to act as one large computer for processing big data using various Apache projects for data access, governance, security and operations. Examples show how Hadoop can be used to analyze real-time streaming data from sensors on trucks to monitor routes, vehicles and drivers.
The document provides information on various components of the Hadoop ecosystem including Pig, Zookeeper, HBase, Spark, and Hive. It discusses how HBase offers random access to data stored in HDFS, allowing for faster lookups than HDFS alone. It describes the architecture of HBase including its use of Zookeeper, storage of data in regions on region servers, and secondary indexing capabilities. Finally, it summarizes Hive and how it allows SQL-like queries on large datasets stored in HDFS or other distributed storage systems using MapReduce or Spark jobs.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
