[jira] Commented: (HADOOP-4187) Create a MapReduce-specific ReflectionUtils that handles JobConf and JobConfigurable

["Owen O'Malley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-4187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641281#action_12641281 ] 

Owen O'Malley commented on HADOOP-4187:
---------------------------------------

Just to be clear, the problem is that core/**/utils/ReflectionUtils references mapred/**/mapred/JobConf and JobConfigurable. Clearly before the subprojects split, this needs to be removed. We need a solution for 0.20, so we can't just ignore the problem, unfortunately. I'd suggest that:
  1. We make a package private mapred.ReflectionUtils that uses JobConf and JobConfigurable. 
  2. Make the callers in mapred call it.
