Duo Zhang commented on HBASE-16510:
-----------------------------------
CancellableRegionServerCallable will call its parent, RegionServerCallable's
call method, we will reset the RpcController there.
And for RpcRetryingCallable, it is only used in HBaseAdmin for some meta
operations, there is no RpcController in the Callable implementation.
> Reset RpcController before retry
