> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 0.20.205.0, 0.23.0
> Environment: Java, Redhat EL, Ubuntu
> Reporter: Eric Yang
> Assignee: Eric Yang
> Fix For: 0.20.205.0, 0.23.0

>
> 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.
