Review request for Ambari.


Bugs: AMBARI-14678
    https://issues.apache.org/jira/browse/AMBARI-14678


Repository: ambari


Description
-------

STR:
HDP 2.2
Multiple Oozie Servers
RU to HDP 2.3

The pre-upgrade directive for Oozie has 
```
<pre-upgrade>
  <task xsi:type="execute" hosts="all" summary="Shut down all Oozie servers">
    <script>scripts/oozie_server.py</script>
    <function>stop</function>
  </task>

  <task xsi:type="execute" hosts="any" summary="Upgrading the database and 
creating a new sharelib">
    <script>scripts/oozie_server_upgrade.py</script>
    <function>upgrade_oozie_database_and_sharelib</function>
  </task>
</pre-upgrade>
```

Notice that the first task runs on all hosts, and the second task runs on 
exactly one random host. The problem is that the scheduler runs both tasks in 
one stage on the union of these hosts. Therefore, the 2nd task runs on the 
wrong set of hosts.
