Date Wed, 09 Feb 2011 20:18:57 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12992700#comment-12992700
] 

Scott Chen commented on MAPREDUCE-2311:
---------------------------------------

The failed tests TestSimulator* are because of timeout.
TestBlockFixer failed because of tasktracker crashed. All failed tests are not related to
this patch.
