http://biforbeginners.blogspot.in/2012/07/step-by-step-installation-of-hadoop-on.html


1)Extract HBase in /usr/local/hbase-0.92.1

$ cd /usr/local
$ sudo tar xzf hbase-0.92.1.tar.gz
$ sudo chown -R hduser hbase-0.92.1

2) In HBase-env.sh

For master and slaves,add or uncomment these

 export JAVA_HOME=/usr/java/jdk1.6.0_33
 export HBASE_CLASSPATH=/usr/local/hadoop/conf
 export HBASE_HEAPSIZE=1000

 export HBASE_OPTS="-XX:+UseConcMarkSweepGC"
 export HBASE_MANAGES_ZK=true

3) In Hbase-site.xml

For master and slaves,add

 

      hbase.rootdir
      hdfs://master:54310/hbase
       
  
      hbase.cluster.distributed
      true

  
  
      hbase.zookeeper.property.clientPort
      2222
            
 
      hbase.master
      master:60000
      
    
 
      hbase.zookeeper.property.maxClientCnxns
      300

 
 
      dfs.support.append
      true

 
 
      hbase.zookeeper.quorum

      master

 
 
      hbase.zookeeper.property.dataDir
      /usr/local/hadoop/zookeeper/data
           
 

4) In usr/local/hbase-0.92.1/conf/regionservers,write

master

slave

5)Copy the hadoop-core-0.20.203.0.jar in 

hadoop folder to the hbase/lib folder.

6)Copy commons-configuration-1.6.jar from 

hadoop lib folder to hbase lib folder.


7)Create a directory /hadoop/zookeeper/data and insert myid in that

For master

mkdir -p /hadoop/zookeeper/data && echo '0' > /hadoop/zookeeper/data/myid 

For Slaves

mkdir -p /hadoop/zookeeper/data && echo '10' > /hadoop/zookeeper/data/myid

Caution:Make sure you assign permissions to hadoop group and hduser to access this folder,else it will

show permission denied error.
