Fwd: [jira] [Created] (MAPREDUCE-7372) MapReduce set permission too late in copyJar method

[Steve Loughran <st...@cloudera.com.INVALID>]

could someone look at the PR for this,
https://github.com/apache/hadoop/pull/4026

I think it iis ok to go in without tests, but don't want to break things.
if someone else could also review, that would be great

             Summary: MapReduce set permission too late in copyJar method
                 Key: MAPREDUCE-7372
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7372
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 3.3.1
            Reporter: Zhang Dongsheng


while execute copyJar in JobResourceUploader .the setPermission running
after setReplication,but setReplication need permission first.So if we set
restrict umask in project such as 0600, the mapreduce process will fail.

In patch file , I put setPermisson before setReplication.
