hi,
i am running Hbase 1.1.2..when i create a table through phoenix, it could not
proceed..
master keeps retrying but it is not able to get the lock..
It is a single node cluster with master and region server on the same server.
thread dump shows below log..
Any reason why this happens and how to resolve this..and which thread is
holding the lock?
