Subject [jira] [Commented] (MAPREDUCE-3028) Support job end notification in .next /0.23
Date Mon, 24 Oct 2011 15:45:34 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13134163#comment-13134163

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.
