Recognize Jetty bug 1342 and handle it
--------------------------------------

                 Key: MAPREDUCE-2529
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2529
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
    Affects Versions: 0.20.204.0, 0.23.0
            Reporter: Thomas Graves
            Assignee: Thomas Graves


We are seeing many instances of the Jetty-1342 (http://jira.codehaus.org/browse/JETTY-1342).
The bug doesn't cause Jetty to stop responding altogether, some fetches go through but a lot
of them throw exceptions and eventually fail. The only way we have found to get the TT out
of this state is to restart the TT.  This jira is to catch this particular exception (or perhaps
a configurable regex) and handle it in an automated way to either blacklist or shutdown the
TT after seeing it a configurable number of them.
