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 2012-10-17 21:15:33,045 INFO org.apache.hadoop.hbase.master.ActiveMasterManager: Adding ZNode for /hbase/backup-masters/localhost,60000,1350488732582 in backup master directory 2012-10-17 21:15:33,083 INFO org.apache.hadoop.hbase.master.ActiveMasterManager: Current master has this master's address, localhost,60000,1350487401859; master was restarted?

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) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at 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. Calling for help, as I think I am missing something here. Thanks and Regards Pankaj Misra ________________________________ Impetus Ranked in the Top 50 India's Best Companies to Work For 2012.
