Jonathan Eagles commented on TEZ-1393:
--------------------------------------
[~sseth], initially I looked into a ThreadLocalProperties solution but didn't
have the time to test its feasibility. This technique has the added benefit
that user code doesn't need to be written in this same working directory way
and works for multiple LocalClients. If you want I can pursue this idea to see
if it meets our criteria. It is advanced, yes, but not complicated.

> Setting user.dir to the staging-dir has the implication of changing the root
> of the filesystem to the staging directory, which is application specific.
> If using multiple instance of LocalClient within a single JVM - this can get
> problematic, between multiple jobs since the CWD will change in the middle of
> execution - which ends up disallowing usage of relative paths.
