--------------------------------------------

             Summary: Rolling Upgrade support for Storm in HDP 2.3.0.0 to 2.3+
                 Key: AMBARI-10944
                 URL: https://issues.apache.org/jira/browse/AMBARI-10944
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
             Fix For: 2.1.0


In RU from HDP 2.2  -> 2.3.0.0, Storm will not be rolling, so the upgrade pack still needs instructions to deactivate and kill running topologies before upgrading Storm, and to rebuild the topologies after.

In 2.3.0.0, Storm's defaults.yaml will have the property storm.meta.serialization.delegate set to backtype.storm.serialization.GzipThriftSerializationDelegate, so as long as Ambari doesn't override the property, the RU from 2.3.0.0 to 2.3+ will be rolling. So the upgrade pack from Dal to Dal will not need these manual confirmations.

To test this out, deploy HDP 2.3.0.0, then perform and RU to HDP 2.3+, and verify the topologies are still running
