Subject [jira] [Commented] (HADOOP-14320) TestIPC.testIpcWithReaderQueuing fails intermittently
Date Tue, 18 Apr 2017 15:33:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14320?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15972922#comment-15972922
] 

Eric Badger commented on HADOOP-14320:
--------------------------------------

*TestIPC.java:810*
{{verify(spy, timeout(100).times(i + 1)).put(Mockito.<Call>anyObject());}}
The 100ms timeout is too aggressive. If the threads don't start immediately or run more slowly
than this main-line code (aka doesn't finish its call in 100ms), the timeout will cause the
test to fail. This can be recreated by adding a 150ms timeout to the thread's run method.
