Ravi Prakash commented on MAPREDUCE-3028:
-----------------------------------------
On my home computer which is a Fedora 14 with OpenJDK,
TestRMContainerAllocator#testBlackListedNodes fails intermittently. On my work
computer which is a RHEL 5, Sun JAVA SDK, the test passes all the time. The
test passes even after I apply the MAPREDUCE-3028.patch. I don't know what is
the reason for the difference in behavior (could be a number of issues)
@Hitesh: I'll try out your patch when I get back home.
But in the mean while. Is this going to be a blocker for MAPREDUCE-3028.patch?

> Oozie primarily depends on the job end notification to determine when the
> job finishes. In the current version, job end notification is implemented in
> job tracker. Since job tracker will be removed in the upcoming hadoop release
> (.next), we wander where this support will move. I think this best effort
> notification could be implemented in the new Application Manager as one of
> the last step of job completion.
> Whatever implementation will it be, Oozie badly needs this feature to be
> continued in next releases as well.
