             Summary: Ambari is overwriting the content of the topology script, even custom
                 Key: AMBARI-12662
                 URL: https://issues.apache.org/jira/browse/AMBARI-12662
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.1.1


Ambari is overwriting the contents of whatever net.topology.script.file.name
is set to. This makes it impossible for a user to manage topology scripts on
their own (if they have an existing script, it keeps getting blown over)

<https://github.com/apache/ambari/blob/trunk/ambari-
server/src/main/resources/stacks/HDP/2.0.6/hooks/before-
START/scripts/params.py#L197>

Regardless if net.topology.script.file.name is set, Ambari should only manage
/etc/hadoop/conf/topology.py and NOT read the net.topology.script.file.name
property and overwrite that file's content. If a user chooses to manage their
own topology script and set that property accordingly, they should be ok doing
that and Ambari should not touch it.
