[jira] [Updated] (MAPREDUCE-1238) mapred metrics shows negative
count of waiting maps and reduces

Thomas Graves updated MAPREDUCE-1238:

Attachment: MAPREDUCE-1238-branch-1.patch
There is no unit test along with this, I don't see any easy way to add one since its a race condition as to when the kill happens. I've manually tested it and made sure the kill comes in before init, during init, and after init and verified the waiting_* metrics correct after each.
