Description
In a cluster where RS Group endpoint is installed, I noticed the following in master log:
2017-12-13 21:42:14,230 ERROR [RpcServer.default.FPBQ.Fifo.handler=29,queue=2,port=20000] master.TableStateManager: Unable to get table ltt-diff state

It seems RSGroupAdminEndpoint#preCreateTable should take into account that the table doesn't exist and avoid the extraneous TableNotFoundException .
