Subject [jira] Commented: (HADOOP-6041) TestKillSubProcesses fails with assertion failure sometimes
Date Mon, 15 Jun 2009 05:48:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6041?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12719406#action_12719406
] 

Sreekanth Ramakrishnan commented on HADOOP-6041:
------------------------------------------------

Is this failure related to the patch or was it found in Trunk builds?

In following trunk builds the test case successfully passed after changes to {{TestKillSubProcesses}}
were put in.
