Assuming that you have setup hadoop 2X as described in Setting Up Hadoop 2.6.0 If not please Do that first
Step 1.1 : Hbase Installation - Download and Extract hbase
I’ve downloaded hbase from the Hbase-1.0.1 Download
mkdir /opt/hbase
cd /opt/hbase
wget http://mirrors.koehn.com/apache/hbase/hbase-1.0.1/hbase-1.0.1-bin.tar.gz
tar xzf hbase-1.0.1-bin.tar.gz
sudo ln -s hbase-1.0.1 currentStep 1.2 : Hbase Installation - Configuring hbase-env.sh
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. I have my Java installed at /opt/java/current. Setup yours accordingly
Configuration files can be found at /opt/hbase/current/conf
export JAVA_HOME=/opt/java/currentStep 1.3 : Hbase Installation - Configuring hbase-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://cyborg:9000/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/opt/hadoop/data/zookeeper</value>
</property>
</configuration>Step 2.1 : Starting Hbase
Start hbase by executing the following command
/opt/hbase/current/bin/start-hbase.shShould give you the following output
localhost: starting zookeeper, logging to /opt/hbase/current/bin/../logs/hbase-vishnu-zookeeper-cyborg.out
starting master, logging to /opt/hbase/current/bin/../logs/hbase-vishnu-master-cyborg.out
starting regionserver, logging to /opt/hbase/current/bin/../logs/hbase-vishnu-1-regionserver-cyborg.outStep 2.2 : Verifying if Hbase is storing files on hdfs
Run the following command to verify if hbase files are on hdfs
$ /opt/hadoop/current/bin/hadoop fs -ls /hbase

After Installing HBase successfully, you can start HBase Shell. below is a list of commands executed on hbase shell.
$ /opt/hbase/current/bin/hbase shell
