Work Description: ZanderXu opened a new pull request, #4660:
URL: https://github.com/apache/hadoop/pull/4660
### Description of PR
When I read some code about protocol, I found that only
ClientNamenodeProtocolPB proxy with RPC timeout, other protocolPB proxy without
RPC timeout, such as RefreshAuthorizationPolicyProtocolPB,
RefreshUserMappingsProtocolPB, RefreshCallQueueProtocolPB,
GetUserMappingsProtocolPB and NamenodeProtocolPB.
If proxy without rpc timeout, it will be blocked for a long time if the NN
machine crash or bad network during writing or reading with NN.
So I feel that we should enable RPC timeout for all ProtocolPB.
