Alejandro Fernandez commented on AMBARI-11009:
----------------------------------------------

1. In HDP 2.3, when installing multiple nimbus servers, the service check fails. To resolve this, modify the cmd as follows,
{code}storm jar /tmp/wordCount.jar storm.starter.WordCountTopology WordCount{unique}{code} if nimbus.seeds is supported and in the storm configs.

2. 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

3. Currently, the nimbus.seeds property is marked as final and cannot be edited in the UI, so this needs to change to enable Nimbus HA
