[jira] [Created] (HDFS-16703) Enable RPC Timeout for some protocols of NameNode.

ZanderXu created HDFS-16703:
-------------------------------

             Summary: Enable RPC Timeout for some protocols of NameNode.
                 Key: HDFS-16703
                 URL: https://issues.apache.org/jira/browse/HDFS-16703
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: ZanderXu
            Assignee: ZanderXu


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.
