[jira] Created: (HADOOP-6833) IPC leaks call parameters when exceptions thrown

IPC leaks call parameters when exceptions thrown
------------------------------------------------

                 Key: HADOOP-6833
                 URL: https://issues.apache.org/jira/browse/HADOOP-6833
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.20.2, 0.21.0, 0.22.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Blocker
         Attachments: hadoop-6833.txt

HADOOP-6498 moved the calls.remove() call lower into the SUCCESS clause of receiveResponse(), but didn't put a similar calls.remove into the ERROR clause. So, any RPC call that throws an exception ends up orphaning the Call object in the connection's "calls" hashtable. This prevents cleanup of the connection and is a memory leak for the call parameters.
