-Re: Setting the HADOOP_HOME_DIR

Adam, my apologies, you are correct. I meant to refer to the
HADOOP_CONF_DIR -- this is what I get for posting before I've had enough
I want to put the CONF and LOGS directories outside of the /usr/hadoop
structure -- this will make it easier to manage with Puppet, and prevent
accidental overwrites during upgrades etc.
