Subject [jira] [Commented] (HADOOP-10062) TestMetricsSystemImpl#testMultiThreadedPublish fails on trunk
Date Sat, 09 Nov 2013 03:21:21 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10062?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13817981#comment-13817981
] 

Shinichi Yamashita commented on HADOOP-10062:
---------------------------------------------

I tested the patch only for fixing of the barrier. But, the failure of the test sometimes
occurred.
I dumped the values of metrics in MetricsSystemImpl#publishMetrics method.  And timestamp
in the record seems to reverse at the time of the failure (HADOOP-10062-failed.txt).
In other words a order to call MetricsSystemImpl#publishMetrics seems to have a problem.
