Subject [jira] [Commented] (MAPREDUCE-6768) TestRecovery.testSpeculative failed with NPE
Date Fri, 26 Aug 2016 19:29:20 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6768?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15439643#comment-15439643
] 

Jason Lowe commented on MAPREDUCE-6768:
---------------------------------------

bq. I guess I must be following some bad practice I have seen in the code base.

It's not a terrible practice, just that I've been sensitive to unnecessarily long sleeps in
unit tests lately.  See the discussion at YARN-5393 for details.

+1 pending Jenkins.  The patch still can't be used as-is on other branches since JDK7 will
want task1Attempt2 to be final for use in the inner class, but that's something I can easily
fix during the commit.
