Date Thu, 30 Oct 2008 19:16:44 GMT
Deadlock in RPC Server
----------------------

                 Key: HADOOP-4552
                 URL: https://issues.apache.org/jira/browse/HADOOP-4552
             Project: Hadoop Core
          Issue Type: Bug
    Affects Versions: 0.16.3
            Reporter: Raghu Angadi
            Assignee: Raghu Angadi



RPC server could get into a deadlock especially when clients or server are network starved.
This is a deadlock between RPC responder thread trying to check if there are any connection
to be purged and RPC handler trying to queue a response to be written by the responder.

This was first observed [this thread|http://www.nabble.com/TaskTrackers-disengaging-from-JobTracker-to20234317.html].
