Subject [jira] [Created] (AMBARI-10944) Rolling Upgrade support for Storm in HDP to 2.3+
Date Tue, 05 May 2015 22:22:00 GMT
Alejandro Fernandez created AMBARI-10944:

             Summary: Rolling Upgrade support for Storm in HDP to 2.3+
                 Key: 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  ->, 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, 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 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, then perform and RU to HDP 2.3+, and verify the topologies
are still running
