-----------------------------------------------
I am getting the error.
{code}
2013-04-03 18:32:31,637 ERROR
org.apache.hadoop.hbase.master.handler.CreateTableHandler: Error trying to
create the table TestTable
{code}
But we do not clear the ENABLING znode. We need that for recreating incase of
master failover. But here the znode is available but the Meta does not have
any entry and hence on master restart we get this error.
