Subject [jira] [Updated] (HADOOP-10090) Jobtracker metrics not updated properly after execution of a mapreduce job
Date Mon, 18 Nov 2013 16:49:21 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10090?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ivan Mitic updated HADOOP-10090:

    Attachment: HADOOP-10090.branch-1.3.patch

Attaching a patch that goes with option #2 and addresses all the comments.

Luke, doing only the backport is not enough, the bug from this Jira will remain. 

Now we have to decide whether to do the backport in this Jira or not. Whether we do it now
or separately, I'd recommend that we change MetricsSourceAdapter#getMetrics signature only
to accept MetricsBuilderImpl parameter. This is a package private method so this change should
be ok. Thoughts?

> After executing a wordcount mapreduce sample job, jobtracker metrics are not updated
properly. Often times the response from the jobtracker has higher number of job_completed
than job_submitted (for example 8 jobs completed and 7 jobs submitted).
