Subject [jira] [Commented] (MAPREDUCE-4456) LocalDistributedCacheManager can get an ArrayIndexOutOfBounds when creating symlinks
Date Mon, 30 Jul 2012 15:33:35 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13424917#comment-13424917
] 

Robert Joseph Evans commented on MAPREDUCE-4456:
------------------------------------------------

After talking with Arun on MAPREDUCE-4493.  He feels that the current MR2 behavior is correct,
and we should just document the differences.  I am fine with going that rout so I will just
update the test to expect the new behavior, and then document that behavior on the other JIRA.
