Subject Zookeeper error in case of multinode hbase cluster
Date Mon, 08 Oct 2012 13:43:14 GMT

I created 2 node hbase cluster with master and a slave .When i try to list
the tables present in hbase  from master and slave , its working fine .But
,if i tried scaning the table or creating a new table or scanning after
this, i 'm getting the following errors

error 1: (in master)

12/10/08 18:53:31 ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists
failed after 3 retries
12/10/08 18:53:31 WARN zookeeper.ZKUtil: hconnection Unable to set watcher
on znode /hbase/master  ---

error 2 :(in master)

ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times

error 3 : ( in slave )

ERROR: org.apache.hadoop.hbase.
PleaseHoldException: org.apache.hadoop.hbase.PleaseHoldException: Master is

Here is some help for this command:
Create table; pass table name, a dictionary of specifications per
column family, and optionally a dictionary of table configuration.
Dictionaries are described below in the GENERAL NOTES section.

My zookeeper configuration in hbase-env.sh is
export HBASE_MANAGES_ZK=true

Please help me out in solving it .
