Hi All,
I have been using HBase 0.94.1 with Hadoop 0.23.1. I had the complete setup in
a pseudo-distributed mode, and was running fine.
Today I had to reset and reformat the namenode and clear all the data as well
to have a fresh run, but since then Hbase is not working as expected. For
instance I am able to list the tables but cannot create new one, it reports
that Master is initializing, as seen from the exception below
hbase(main):004:0> create 'testrun','samplecf'
ERROR: org.apache.hadoop.hbase.PleaseHoldException:
org.apache.hadoop.hbase.PleaseHoldException: Master is initializing
at
org.apache.hadoop.hbase.master.HMaster.checkInitialized(HMaster.java:1626)
at org.apache.hadoop.hbase.master.HMaster.createTable(HMaster.java:1154)

org.apache.hadoop.hbase.ipc.WritableRpcEngine$Server.call(WritableRpcEngine.java:364)
at
org.apache.hadoop.hbase.ipc.HBaseServer$Handler.run(HBaseServer.java:1400)
In order to resolve this I have even tried to delete the root so that hbase can
recreate it fresh. HBase is able to recreate the ROOT but this issue persists.
I am also not able to connect via native java client, as it does not get
reference of the Master.
Additionally I see the following error in the HBase Master logs
2012-10-17 21:15:33,043 ERROR
org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper: Node /hbase/master
already exists and this is not a retry

Calling for help, as I think I am missing something here.
Thanks and Regards
Pankaj Misra
