Subject [jira] Created: (HADOOP-3881) IPC client doesnt time out if far end handler hangs

IPC client doesnt time out if far end handler hangs
---------------------------------------------------

                 Key: HADOOP-3881
                 URL: https://issues.apache.org/jira/browse/HADOOP-3881
             Project: Hadoop Core
          Issue Type: Bug
          Components: ipc
            Reporter: Steve Loughran
            Priority: Minor


This is what appears to be happening in some changes of mine that (inadventently) blocked
JobTracker: if the client can connect to the far end and invoke an operation, the far end
has forever to deal with the request: the client blocks too.

Clearly the far end shouldn't do this; its a serious problem to address. but should the client
hang? Should it not time out after some specifiable time and signal that the far end isn't
processing requests in a timely manner? 

(marked as minor as this shouldn't arise in day to day operation. but it should be easy to
create a mock object to simulate this, and timeouts are considered useful in an IPC)
