Review request for Ambari and Alejandro Fernandez.
Bugs: AMBARI-14408
https://issues.apache.org/jira/browse/AMBARI-14408
Repository: ambari
Description
-------
Need to back up common services folder when running ambari RPM upgrade.
Otherwise, if an older version of a given common service is removed, the
ambari-server upgrade cmd run will fail with error about the service (older
version, removed in newer ambari release) dir does not have a valid
metainfo.xml file.
Diffs

Diff: https://reviews.apache.org/r/41555/diff/
Testing
-------
1. install ambari 2.1.2/hdp 2.2,
2. customize the common service in ambari trunk to make a new dir representing
a newer version of solr,
3. build ambari server rpm from ambari trunk code,
4. run yum upgrade -y ambari-server (against a local repo)
Verify
1. the common-services dir from the older ambari server rpm install was backed
up as common-services-<timestamp>.old,
2. a new common-services dir was installed during the yum upgrade cmd run
3. was able to run ambari-server upgrade cmd successfully and start ambari
server successfully
Thanks,
Di Li
