Review request for Ambari and Alejandro Fernandez.
Bugs: AMBARI-14052
https://issues.apache.org/jira/browse/AMBARI-14052
Repository: ambari
Description
-------
While doing Express Upgrade of stack from HDP 2.1 -> 2.3, the following issues
were seen for Storm.
- Storm Config /etc/storm/conf is incorrectly pointing to
/etc/alternatives/storm-conf.
- Restarting the Storm supervisor fails (Attached Screenshot).
Resolution :
1. Fixed the conf_select.py for conf symlink. In case, '/etc/storm/conf' does
have a symlink and it's not the correct one (eg: /etc/alternatives/storm-conf),
we remove the symlink and make it point to correct symlink (eg:
/etc/storm/2.3.x.y-<vesrion>/0).
2. Fixed the Storm Supervisor failure, by adding the tasks required in
2.1/nonrolling-upgrade-2.3.xml for "Zookeeper and Storm local data removal".
