Am not sure of the above failure. The same setup is able to create new tables.
Now the table is already in ENABLING state. The master was restarted.
Now as the table was found in ENABLING state but not added to META the EnableTableHandler

This does not allow me to start my master further leading to unoperationable state of the whole cluster.
