-Re: tar.gz to cdh3 package

Sorry, to be more verbose, CDH3 actually respects permissions inside of
HDFS, and creates special users called "hdfs" and "mapred" to keep things
safe. I'm guessing by default when I did the non-package install, I didn't
enable permissions and/or installed everything as the same user so I didn't
So, that makes getting the permissions right for /tmp more important, but I
didn't think the hadoop crowd would care since it's pig that causes the
write to that location. But a newbie pig user might need the FYI....
