Review request for Ambari, Andrew Onischuk and Dmitro Lisnichenko.


Bugs: AMBARI-5264
    https://issues.apache.org/jira/browse/AMBARI-5264


Repository: ambari


Description
-------

*STR:*
1) Deploy cluster by default
2) Go to Ganglia service page -> Config tab 
3) Change value "Ganglia rrdcached base directory" (e.g. /var/lib/ganglia/rrd8)
4) Restart Ganglia
5) Change "Ganglia rrdcached base directory" back to old value (by default - /var/lib/ganglia/rrds)
6) Restart Ganglia

*Expected result:* Ganglia should be restarted successfully
*Current result:* Ganglia Server goes to "installed" state and stuck there
