Review request for Ambari, Dmytro Grinenko, Dmitro Lisnichenko, Jonathan
Hurley, Jayush Luniya, and Nate Cole.
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.
