Siddharth Seth updated TEZ-1879:
--------------------------------
    Attachment: TEZ-1879.3.txt

Thanks for the review. Updated patch.

bq. Can the above ugi instantiation be done in the DAGAppMaster constructor 
itself?
Fixed.

bq. LocalClient uses amCredentials where as the AM itself uses amTokens - a bit 
confusing. Probably does not need a change right now but might be helpful for 
readability.
Will rename amTokens to amCredentials just before commit.

[~hitesh] - do you want to look at this again, or should i commit it.

> Modifying the client UGI can cause issues when the client tries to submit 
> another job - or has tokens already populated in the UGI.
