HBase 0.98.4 Installation & Configuration

HBase is a column-oriented database management system that runs on top of Hadoop Distributed File System (HDFS). HBase can host very large tables, billions of rows, millions of columns and can provide real-time, random read/write access to Hadoop data.HBase scales linearly across very large datasets and easily combines data sources with different structures and schemas.

Unpack  hbase-0.98.4-hadoop2-bin.tar.gz file.

$ cd /usr/local $ sudo tar –xvf hbase-0.98.4-hadoop2-bin.tar.gz

Rename hbase-0.98.4-hadoop2-bin to hbase

$ sudo mv hbase-0.98.4-hadoop2 hbase

Setting up environment for HBase

Edit ~/.bashrc file for set up the HBase environment by appending the following lines.

$ sudo nano ~/.bashrc

export HBASE_HOME=/usr/local/hbase export PATH=$HBASE_HOME/bin:$PATH

Reload the configuration file ~/.bashrc with the following command.

$ cd /usr/local/hbase/conf $ sudo nano hbase-env.sh

Set value for following environment variable.

export JAVA_HOME=/usr/local/jdk export HBASE_REGIONSERVERS=/usr/local/hbase/conf/regionservers export HBASE_MANAGES_ZK=true

Change the ownership and permissions of the directory /usr/local/hbase

$ sudo chown -R hdfs:hdfs /usr/local/hbase $ sudo chmod -R 755 /usr/local/hbase

Edit Configuration Files

Edit hbase-site.xml and place the following properties inside the file.

$ cd /usr/local/hbase/conf $ sudo nano hbase-site.xml

<configuration>  <property>   <name>hbase.rootdir</name>   <value>hdfs://localhost:9000/hbase</value>  </property>  <property>   <name>hbase.cluster.distributed</name>   <value>true</value>  </property>  <property>   <name>hbase.zookeeper.quorum</name>   <value>localhost</value>  </property>  <property>   <name>dfs.replication</name>   <value>1</value>  </property>  <property>   <name>hbase.zookeeper.property.clientPort</name>   <value>2181</value>  </property>  <property>   <name>hbase.zookeeper.property.dataDir</name>   <value>/home/hduser/hbase/zookeeper</value>  </property> </configuration>
