Allen Wittenauer commented on HADOOP-11460:
-------------------------------------------
One subtle bug which we both missed. sbin/yarn-daemon.sh is somehow setting
HADOOP_CONF_DIR and YARN_CONF_DIR to "YARN_CONF_DIR". I suspect it has
something to do with null values not getting handled properly.

> It is a very common shell pattern in 3.x to effectively replace sub-project
> specific vars with generics. We should have a function that does this
> replacement and provides a warning to the end user that the old shell var is
> deprecated. Additionally, we should use this shell function to deprecate the
> shell vars that are holdovers already.
