Chris Nauroth commented on HADOOP-10090: ---------------------------------------- +1 for version 4 of the branch-1 patch. I also was mistaken in thinking there were 2 separate race conditions: one around the JMX cache and another around the update from the metrics sources. If always pushing all metrics is sufficient to fix the problem in Ivan's tests, then I think we're good. > Jobtracker metrics not updated properly after execution of a mapreduce job > -------------------------------------------------------------------------- > > Key: HADOOP-10090 > URL: https://issues.apache.org/jira/browse/HADOOP-10090 > Project: Hadoop Common > Issue Type: Bug > Components: metrics > Affects Versions: 1.2.1 > Reporter: Ivan Mitic > Assignee: Ivan Mitic > Attachments: HADOOP-10090.branch-1.2.patch, > HADOOP-10090.branch-1.3.patch, HADOOP-10090.branch-1.4.patch, > HADOOP-10090.branch-1.patch, OneBoxRepro.png > > > After executing a wordcount mapreduce sample job, jobtracker metrics are not > updated properly.
