Subject [jira] Updated: (HADOOP-6463) Uninformative error message for some sort of file permission problem from the hadoop command
Date Sat, 19 Feb 2011 22:52:38 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6463?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benson Margulies updated HADOOP-6463:
-------------------------------------

    Status: Open  (was: Patch Available)

Let's see: 11 months from submission to first response (which I somehow missed) on a trivial
patch that any concerned committer could adapt to current code in 5 seconds if the problem
still exists.
