HBase Installation

The prerequisite for HBase installation are Java and Hadoop installed on your Linux machine.

Hbase can be installed in three modes: standalone, Pseudo Distributed mode and Fully Distributed mode.

Download the Hbase package from http://www.interior-dsgn.com/apache/hbase/stable/ and unzip it with the below commands.

$cd usr/local/$wget http://www.interior-dsgn.com/apache/hbase/stable/hbase-0.98.8-hadoop2-bin.tar.gz
$tar -zxvf hbase-0.98.8-hadoop2-bin.tar.gz

Login as super user as shown below

$su
$password: enter your password here
mv hbase-0.99.1/* Hbase/

Configuring HBase in Standalone Mode

Set the java Home for HBase and open hbase-env.sh file from the conf folder. Edit JAVA_HOME environment variable and change the existing path to your current JAVA_HOME variable as shown below.

cd /usr/local/Hbase/conf
gedit hbase-env.sh

Replace the existing JAVA_HOME value with your current value as shown below.

export JAVA_HOME=/usr/lib/jvm/java-1.7.0

Inside /usr/local/Hbase you will find hbase-site.xml. Open it and within configuration add the below code.

<configuration>
   //Here you have to set the path where you want HBase to store its files.
<property>
<name>hbase.rootdir</name>
<value>file:/home/hadoop/HBase/HFiles</value>
</property>
	
   //Here you have to set the path where you want HBase to store its built in zookeeper  files.
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/hadoop/zookeeper</value>
</property>
</configuration>

Now start the Hbase by running the start-hbase.sh present in the bin folder of Hbase.

$cd /usr/local/HBase/bin
$./start-hbase.sh

Cloudera VM is recommended as it has Hbase preinstalled on it.

Starting Hbase: Type Hbase shell in terminal to start the hbase.
