Subject [jira] [Updated] (MAPREDUCE-4629) Remove JobHistory.DEBUG_MODE
Date Fri, 07 Sep 2012 16:14:08 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4629?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Joseph Evans updated MAPREDUCE-4629:
-------------------------------------------

    Attachment: trunk-mr-6429.patch

Uploading the trunk patch again, unchanged to Jenkins can run the precommit build on it.

The changes look good to me.  Assuming Jenkins comes back OK I am a +1 on the changes for
trunk.  Assuming my running the unit tests on branhc-1 come back OK I am +1 for that as well.

> Remove JobHistory.DEBUG_MODE for the following reasons:
> 1. No one seems to be using it - the config parameter corresponding to enabling it does
not even exist in mapred-default.xml
> 2. The logging being done in DEBUG_MODE needs to move to LOG.debug() and LOG.trace()
> 3. Buggy handling of helper methods in DEBUG_MODE; e.g. directoryTime() and timestampDirectoryComponent().
