> Following is the scenario:
> Start RS and Active and standby masters
> Create table and insert data.
> Disable the table.
> Stop the active master and switch to the standby master.
> Now enable the table.
> Do a scan on the enabled table.
> NotServingRegionException is Thrown.
> But the same works well when we dont switch the master.
