HBase - Zookeeper Error.

[dhamodharan . ramalingam]

Hi,

I am using Hadoop 2.5.1 and HBase 0.98.8. 

I an getting the following error when I give some command in hbase shell, 
I am using internal zookeeper.

2014-12-01 20:02:19,282 ERROR [main] 
client.HConnectionManager$HConnectionImplementation: The node /hbase is 
not in ZooKeeper. It should have been written by the master. Check the 
value configured in 'zookeeper.znode.parent'. There could be a mismatch 
with the one configured in the master.

Find my hbase-site.xml below.
