Eric Yang commented on HADOOP-5291:
-----------------------------------

I think if CHUKWA_HOME is not defined, we might want to bail out instead of using /tmp/chukwa as CHUKWA_HOME.  This will make Chukwa less platform dependent.

> If Chukwa is started in such a way that CHUKWA_HOME doesn't get set, then pid files are stored in chukwa/null/var....  This comes up if, e.g., the agent is started within eclipse.  We can make this case look prettier by defaulting to /tmp.
