Review request for Ambari, Alejandro Fernandez, Dmitro Lisnichenko, and Nate Cole.


Bugs: AMBARI-14819
    https://issues.apache.org/jira/browse/AMBARI-14819


Repository: ambari


Description
-------

When performing a rolling upgrade from HDP 2.3 to 2.4, Storm topologies are stopped. The upgrade pack for HDP 2.3 to 2.4 was copied from HDP 2.2 to 2.3 - in HDP 2.2, Storm did not support rolling upgrades and the removal of local and ZK data was necessary.

Testing
-------

Upgraded storm from HDP 2.3 to HDP 2.4 and verified that the local and ZK data was not removed.


Thanks,

Jonathan Hurley
