[jira] Updated: (MAPREDUCE-1241) JobTracker should not crash when
mapred-queues.xml does not exist
[ https://issues.apache.org/jira/browse/MAPREDUCE-1241?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Todd Lipcon updated MAPREDUCE-1241:
-----------------------------------
Attachment: mapreduce-1241.txt
Patch adds a mapred-queues-default.xml into the mapreduce jar (copied from the mapred-queues.xml in the conf/ dir). QueueManager now falls through to the -default version if mapred-queues.xml is not found on the classpath.
Added a unit test for this and also tested manually.

> Currently, if you bring up the JobTracker on an old configuration directory, it gets a NullPointerException looking for the mapred-queues.xml file. It should just assume a default queue and continue.
