Prakash Khemani updated HBASE-4696:
-----------------------------------

    Description: 
HRegionThriftServer.getRowWithColumnsTs() redirects the request to the correct 
region server if it has landed on the wrong region-server. With this approach 
the smart-client will never get a NotServingRegionException and it will never 
be able to invalidate its cache. It will indefinitely send the request to the 
wrong region server and the wrong region server will always be redirecting it.

Either redirects should be turned off and the client should react to 
NotServingRegionExceptions.

Or somehow a flag should be set in the response telling the client to refresh 
its cache.
