Dustin Cote commented on YARN-2369:
-----------------------------------

[~jlowe] or [~aw] is this one still needed?  If it is, I'd like to take a crack at it.  I've had problems with the LD_LIBRARY_PATH in my own experiences, so if it's not fixed by something else in a later version I think it should be.

> When processing environment variables for a container context the code assumes that the value should be appended to any pre-existing value in the environment.  This may be desired behavior for handling path-like environment variables such as PATH, LD_LIBRARY_PATH, CLASSPATH, etc. but it is a non-intuitive and harmful way to handle any variable that does not have path-like semantics.
