-----------------------------------------------
The znode lock is ephemeral sequential znode.
{code}
return ZKUtil.createNodeIfNotExistsNoWatch(zkWatcher, fullyQualifiedZNode,
metadata, CreateMode.EPHEMERAL_SEQUENTIAL);
{code}
> Create table handler needs to handle failure cases.

> IOExceptions are common while creation of regioninfos, htableDescriptors etc.
> After this exception if i try to recreate the table using admin, we need to
