Apache HBase with MapR

Introduction

Apache HBase [1] is an open-source, distributed, versioned, column-oriented store modeled after Google' Bigtable: A Distributed Storage System for Structured Data by Chang et al.[2] Just as Bigtable leverages the distributed data storage provided by the Google File System, HBase provides Bigtable-like capabilities on top of Apache Hadoop [3].

To get started using HBase, the full documentation for this release can be found under the doc/ directory that accompanies this README. Using a browser, open the docs/index.html to view the project home page (or browse to [1]). The HBase 'book' at docs/book.html has a 'quick start' section and is where you should being your exploration of the HBase project.

The latest HBase can be downloaded from an Apache Mirror [4].

The source code can be found at [5]

Compiling HBase with MapR patches

Clone and checkout the "<hbase-version>-mapr" tag or branch of the Apache HBase release version from the github (https://github.com/mapr/hbase). For example, if you want to compile HBase version 0.98.4, checkout the "0.98.4-mapr" branch.

$ mkdir hbase-0.98.4-mapr
$ cd hbase-0.98.4-mapr
$ git clone git://github.com/mapr/hbase.git .
$ git checkout 0.98.4-mapr
$ mvn clean install assembly:single -DskipTests -Dgenerate.mapr.patches

The command line arguments -DskipTests and -Dgenerate.mapr.patches are optional and allow you to skip running the unit test and generate MapR patches applied over the apache release in git serial format, respectively.

Using HBase artifacts with MapR patches in your Maven Project

Add the following dependency to your project's pom.xml

<dependency>
  <groupId>org.apache.hbase</groupId>
  <artifactId>hbase-client</artifactId>
  <version>${mapr.hbase.version}</version>
</dependency>
