    Resolution: Won't Fix

Hello [~skysider]. I noticed you closed pull request [#4629|https://github.com/apache/hadoop/pull/4629]. I assume you are abandoning this change, because 777 would be too dangerous, so I'm also closing this corresponding JIRA issue. (If I misunderstood, and you're still working on something for this, then the issue can be reopened.)

> FSDownload calls createDir in the call method to create the destinationTmp directory, which is later used as the parent directory to create the directory dFinal, which is used in doAs to perform operations such as path creation and path traversal. doAs cannot determine the user's identity, so there is a problem with setting 755 permissions for destinationTmp here, I think it should be set to 777 permissions here.
