Review request for Ambari and Alejandro Fernandez.


Bugs: AMBARI-16140
    https://issues.apache.org/jira/browse/AMBARI-16140


Repository: ambari


Description
-------

When a user runs yum upgrade ambari-agent. The preinstall script backs up the 
stack dir in /var/lib/ambari-agent/cache by renaming it with a stampstamp. The 
same logic should happen for /var/lib/ambari-agent/cache/common-services.


Diffs
-----

  ambari-agent/src/main/package/deb/control/preinst 7265c55 
  ambari-agent/src/main/package/rpm/preinstall.sh d7419d3 

Diff: https://reviews.apache.org/r/46745/diff/


Testing
-------

build ambari-agent RPM, run yum upgrade ambari-agent against a trunk cluster, 
verify /var/lib/ambari-agent/cache/stack and 
/var/lib/ambari-agent/cache/common-services are backed up.


Thanks,

Di Li
