Review request for Ambari, Andrew Onischuk and Dmytro Sen.


Bugs: AMBARI-12101
    https://issues.apache.org/jira/browse/AMBARI-12101


Repository: ambari


Description
-------

- Install Ambari 2.0 based cluster.
- Add a new service (custom) which is not part of the stack using "Add Service" wizard.  This
step requires the new custom service package needs to be copied to the /var/lib/ambari-server/resources/stacks/HDP/2.2/services
folder.
- Deploy the new service and everything works fine.
- Now upgrade from Ambari 2.0 to Ambari 2.0.1

Problem:  The /var/lib/ambari-server/resources/stacks/HDP/2.2/services/mycustomservice folder
got wiped out. Restarting the ambari-server results in the following exception.
{code}
27 May 2015 10:53:55,441 ERROR [main] AmbariServer:667 - Failed to run the Ambari Server
org.apache.ambari.server.StackAccessException: Stack data, stackName=HDP, stackVersion=2.2,
serviceName=HST
	at org.apache.ambari.server.api.services.AmbariMetaInfo.getService(AmbariMetaInfo.java:497)
	at org.apache.ambari.server.api.services.AmbariMetaInfo.getComponent(AmbariMetaInfo.java:265)
	at org.apache.ambari.server.controller.utilities.DatabaseChecker.checkDBConsistency(DatabaseChecker.java:96)
	at org.apache.ambari.server.controller.AmbariServer.run(AmbariServer.java:217)
	at org.apache.ambari.server.controller.AmbariServer.main(AmbariServer.java:665)
{code}

Expected: After upgrade the added service should be available and active.  The custom service
folder should not be wiped out from the stacks folder.
