Subject [jira] [Commented] (YARN-2785) TestContainerResourceUsage fails intermittently
Date Sat, 01 Nov 2014 01:39:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14192892#comment-14192892
] 

Zhijie Shen commented on YARN-2785:
-----------------------------------

Add more time should a solution for slow computers. My question is whether all test cases
in TestContainerResourceUsage are subject to timeout? And it seems that both testUsageWithOneAttemptAndOneContainer
and testUsageWithMultipleContainersAndRMRestart need to sleep to let metrics to accumulate.
Hence should the fix be applied to all the test cases here?
