Daryn Sharp commented on MAPREDUCE-6021:
----------------------------------------
I think for uber mode to be complete transparent, the logic should be identical
to {{TaskAttemptImpl}}. Ie. use {{crossPlatformifyMREnv}} for LD_LIBRARY_PATH
and also set SHELL.
> MR AM should have working directory in LD_LIBRARY_PATH

> Tasks implicitly pick up shared libraries added to the job because the task
> launch context explicitly adds the container working directory to
> LD_LIBRARY_PATH. However the same is not done for the AM container which is
> inconsistent. User code can run in the AM via output committer, speculator,
> uber job, etc., so the AM's LD_LIBRARY_PATH should have the container work
> directory for consistency with tasks.
