> To avoid compatibility issues with older versions HBaseAdmin#isTableEnabled returning
true even if the table state is null. Its also returning true even a table is not present.
We should confirm table existence from .META. before checking in zk. If table not present
or deleted, then It will throw TableNotFoundException.
