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.
