Subject [jira] Commented: (MAPREDUCE-911) TestTaskFail fail sometimes
Date Tue, 25 Aug 2009 06:47:59 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-911?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12747260#action_12747260
] 

Amareshwari Sriramadasu commented on MAPREDUCE-911:
---------------------------------------------------

TestTaskFail fails first 2 attempts and passes in thrid attempt. 
>From the logs, it shows that before 2nd attempt could get a chance to run, third attempt
is launched speculatively, which leads to job completion.
So, speculation-execution should be disabled for the test.
