Chris Nauroth commented on HADOOP-12294:
----------------------------------------

[~lichangleo], thanks for the clarification about the original intent of the 
patch.

Is it worth considering fully eliminating {{dfs.umask}} from trunk?  We're 
already at a point where the change is backwards-incompatible.  It has been 
deprecated for a long time in 2.x, so maybe it's time just to remove the whole 
thing?

If not, then I think we need to correct this JIRA title and its CHANGES.txt 
entry to avoid confusion.  Reading the title made me think that {{dfs.umask}} 
would stop working altogether.
