Description

In CreateTable Handler there are number of 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 remove the acquired table lock and also clear the ZKTable in memory cache so that the operation can be retried.
