             Summary: Empty package folders on ambari-server causes corresponding component restart to fail
                 Key: AMBARI-13019
                 URL: https://issues.apache.org/jira/browse/AMBARI-13019
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.0
            Reporter: Nahappan Somasundaram
            Assignee: Nahappan Somasundaram
             Fix For: 2.2.0


When the agent executes a command say status/start/stop command, ambari-server provides the service_package_folder to use as a parameter 

Repro Steps:
1. mkdir /var/lib/ambari-server/resouces/stacks/HDP/2.2/services/HDFS/package
2. ambari-server restart
3. Notice HDFS components report Heartbeat Lost and Restart HDFS fail.
4. This is because the sservice_package_folder is set to the empty folder. 
ERROR 2015-08-28 20:35:59,383 CustomServiceOrchestrator.py:218 - Caught an exception while executing custom service command: <class 'ambari_agent.AgentException.AgentException'>: 'Script /var/lib/ambari-agent/cache/stacks/HDP/2.2/services/HDFS/package/scripts/namenode.py does not exist'; 'Script /var/lib/ambari-agent/cache/stacks/HDP/2.2/services/HDFS/package/scripts/namenode.py does not exist'
Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/ambari_agent/CustomServiceOrchestrator.py", line 151, in runCommand
    script_path = self.resolve_script_path(base_dir, script)
  File "/usr/lib/python2.6/site-packages/ambari_agent/CustomServiceOrchestrator.py", line 288, in resolve_script_path
    raise AgentException(message)

So even if we disable the stack from replicating an empty folder, the ambari-server would still pass the path as empty folder. 

We should also look at ignoring empty package folders while building the Stack Inheritance in Ambari Server
