Chris Riccomini commented on MAPREDUCE-3068:
--------------------------------------------
Hey Arun,
Do you want just the putIfAbsent vars specified in the latest patch, or do you
want to modify setEnvFromInputString to putIfAbsent for ALL env variables
specified in admin-env? I have some concern about doing the latter, as it
changes the existing behavior of the setEnv.. method, which is used in MR, not
just YARN.
Thanks!
Chris
