Set default hdfs, mapred uid, and hadoop group gid for RPM packages
-------------------------------------------------------------------

                 Key: HADOOP-7603
                 URL: https://issues.apache.org/jira/browse/HADOOP-7603
             Project: Hadoop Common
          Issue Type: Bug
         Environment: Java, Redhat EL, Ubuntu
            Reporter: Eric Yang
            Assignee: Eric Yang


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.
