Andrew Onischuk created AMBARI-16735:
----------------------------------------

             Summary: HDFS data disk mount point permissions
                 Key: AMBARI-16735
                 URL: https://issues.apache.org/jira/browse/AMBARI-16735
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.4.0


You can't change the ownership of the datanode data mount points to
hdfs:hadoop before beginning the installation as the user and group won't
exist, they're created by the rpm's deployed by ambari.

You could create the user/group yourself and then set the ownership but that
kind of defeats the purpose of having ambari and the agents to perform that
task for you.

Would be nice if Ambari could chmod dfs.datanode.data.dir during install.
