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.
