    • Release Note:
      Set hdfs uid, mapred uid, and hadoop gid to fixed numbers (201, 202, and 123, respectively).

      Description

      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:

      uid: 201 for hdfs
      uid: 202 for mapred
      gid: 49 for hadoop
      

      would be free for use.
