Subject [jira] [Commented] (MAPREDUCE-6201) TestNetworkedJob fails on trunk
Date Fri, 24 Feb 2017 19:36:44 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15883389#comment-15883389

Haibo Chen commented on MAPREDUCE-6201:
---------------------------------------

Thanks [~pbacsko] for your patch! While increasing NM_MAX_PER_DISK_UTILIZATION_PERCENTAGE
would definitely make the test less likely to fail because of NM disks going nearly full,
it does not eliminate the issue completely. I suppose it is a general issue for any test that
uses MiniYarnCluster. I wonder if we can add some message in the assert statements to make
it more explicit to diagnose.
