Problem with HBase 0.94 and 0.96

[Sanjay Bhosale]

Can anybody please resolve my this issues.

I have configured HBase (0.94 version) on 2 nodes. When i try to insert the data into table created in HBase through Pig Scripts job remains in pending state (log saying connection refused exception) and then runs after long period.

Then i tried to move to 0.96, where i came across the problem that HMaster gets aborted in the initial state. 

Erros in the log says :

13/10/23 17:05:09 FATAL master.HMaster: Unhandled exception. Starting shutdown.

java.lang.IllegalArgumentException: .META. no longer exists. The table has been renamed to hbase:meta

Now problem is resolved to some extent. Now i am getting error at slaves that they are unable to connect to master.

But master is saying that connection is established successfully.

And also when invoked pig script zookeeper tries for localhost.
