> Key: AMBARI-14678
> URL: https://issues.apache.org/jira/browse/AMBARI-14678
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.2.0
> Reporter: Alejandro Fernandez
> Assignee: Alejandro Fernandez
> Fix For: 2.2.1

> STR:
> HDP 2.2
> Multiple Oozie Servers
> RU to HDP 2.3
> The pre-upgrade directive for Oozie has
> {code}
> <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>
> {code}
> 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.
