Subject [jira] [Updated] (YARN-5608) TestAMRMClient.setup() fails with ArrayOutOfBoundsException
Date Thu, 01 Sep 2016 05:05:21 GMT

     [ https://issues.apache.org/jira/browse/YARN-5608?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rohith Sharma K S updated YARN-5608:
------------------------------------
    Attachment: YARN-5608.patch

Added a assertion to verify number of nodeReports are same as nodeCount. But again test will
fail with added assertion. Real root cause need to find why nodes did not get registered.
May be test run logs will help to know this details
