Robert Nettleton resolved AMBARI-11443.
---------------------------------------

Closing this as a duplicate of AMBARI-11442.  

The bug server was very slow yesterday, and hitting the "Create" button twice while waiting caused two separate bugs to be generated for the same problem.

> The Ambari stack scripts for Yarn currently have a problem regarding the startup of the Yarn Application Timeline Service.
> The timeline service has two properties for DB storage:
> yarn.timeline-service.leveldb-timeline-store.path
> yarn.timeline-service.leveldb-state-store.path
> The current Yarn stack scripts only create a directory for "yarn.timeline-service.leveldb-timeline-store.path" during a cluster startup.  
> If the default settings are used for these properties, then things will work fine, since both are mapped to the same root directory.
> If the two properties are set to different values, then the App Timeline Service will fail to startup, since the directory associated with "yarn.timeline-service.leveldb-state-store.path" will not have been created.  
> The "yarn.timeline-service.leveldb-state-store.path" property was added in Ambari 2.1 in HDP 2.2.  The rest of the Yarn stack code should be updated to use this variable to create a separate directory, if needed.  
> I'm working on a fix for this, and will be submitting a patch shortly.
