Subject [jira] [Commented] (YARN-1522) TestApplicationCleanup.testAppCleanup occasionally fails
Date Fri, 20 Dec 2013 03:10:06 GMT

    [ https://issues.apache.org/jira/browse/YARN-1522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13853620#comment-13853620
] 

Liyin Liang commented on YARN-1522:
-----------------------------------

When the case failed, the log file contains the following line:
{code}
2013-12-19 11:37:42,492 INFO  [main] resourcemanager.TestApplicationCleanup (TestApplicationCleanup.java:testAppCleanup(109))
- Waiting to get cleanup events.. cleanedConts: 0 cleanedApps: 1
{code}
So before the while loop, apps.size() equals to one. During the while loop, after another
heartbeat, apps.size() will be zero. Then after the while loop,
{code}
Assert.assertEquals(1, apps.size());
{code}
fails.
