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.
