body: <p><br>
  I have recently configured hadoop cluster with two machines(on ubuntu). It works fine so far. But when i try to configure hbase on the above hadoop cluster, it shows error.
  Here is what i did,</p>
  
  <p>i have two machines.
  192.168.1.110 Hadoop master
  192.168.1.111 Hadoop slave</p>
  
  <h2>conf/hbase-env.sh</h2>
  
  <p>export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.22
  export HBASE_CLASSPATH=/home/hadoop/hadoop-0.20.2/conf
  export HBASE_MANAGES_ZK=true</p>
  
  <h2>hbase-site.xml</h2>
  
  <p>hbase.master->192.168.1.110:54310(Same as hadoop master:port)
  hbase.rootdir->hdfs://192.168.1.110:54310/hbase
  hbase.cluster.distributed->true
  hbase.zookeeper.quorum->192.168.1.110,192.168.1.111</p>
  
  <p>And region srevers,<br>
  192.168.1.111</p>
  
  <p>After starting hbase, i tried to run the command from hbase shell</p>
  
  <p>hbase(main):001:0> list
  TABLE<br>
  It shows                            </p>
  
  <p>ERROR: org.apache.hadoop.hbase.MasterNotRunningException: null</p>
