Subject [jira] [Commented] (MAPREDUCE-2364) Shouldn't hold lock on rjob while localizing resources.
Date Mon, 08 Aug 2011 17:50:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2364?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13081086#comment-13081086

Devaraj Das commented on MAPREDUCE-2364:
----------------------------------------

Subroto, I see a significant difference in the patches attached to MAPREDUCE-2209 and the
last one here. I'll need to look at the details but if you have time could you please take
a look at the patch attached here and see if this makes sense (given this patch predates the
patch on MAPREDUCE-2209; I am sorry that I didn't look at the patch here earlier).
