Subject [jira] [Updated] (MAPREDUCE-2793) [MR-279] Maintain consistency in naming appIDs, jobIDs and attemptIDs
Date Tue, 21 Feb 2012 18:51:46 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2793?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bikas Saha updated MAPREDUCE-2793:
----------------------------------

    Attachment: MAPREDUCE-2793-branch-0.23.patch

I did not use the helper methods in ConvertorUtils because the currently used one have better
error messages and some tests are testing that proper errors are reported.
Rest fixed. The code in the forName functions are trying to use the same exception code and
 use fall through from catch blocks to do that. I have made the minimal changes to make it
work with the above code flow.
