> Hadoop rpm package creates hdfs, mapped users, and hadoop group for automatically setting up pid directory and log directory with proper permission. The default headless users should have a fixed uid, and gid numbers defined.
> Searched through the standard uid and gid on both Redhat and Debian distro. It looks like:
> {noformat}
> uid: 201 for hdfs
> uid: 202 for mapred
> gid: 49 for hadoop
> {noformat}
> would be free for use.
