Subject [jira] [Commented] (HADOOP-12588) Fix intermittent test failure of TestGangliaMetrics
Date Tue, 28 Jun 2016 13:50:57 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15353002#comment-15353002
] 

Masatake Iwasaki commented on HADOOP-12588:
-------------------------------------------

Thanks for reporting this, [~stevel@apache.org]. The test log of HADOOP-13323 indicates there
is a race with {{TestMetricsSystemImpl}}. The {{TestGangliaMetrics#testGangliaMetrics2}} sets
{{*.period}} to 120 but 8 was used.

2016-06-27 15:21:31,480 INFO  impl.MetricsSystemImpl (MetricsSystemImpl.java:startTimer(375))
- Scheduled snapshot period at 8 second(s).
{noformat}

I will upload additional patch or open another issue if I need major refactoring of the test.
