Ambari 2.0 timeline server on hdfs times out

[Greg Hill <gr...@RACKSPACE.COM>]

If I pass this configuration in to YARN on HDP2.2 using Ambari 2.0:

"yarn.timeline-service.leveldb-timeline-store.path": 'hdfs:///apps/yarn/timeline'

It spins forever waiting to set up the HDFS paths for me.  I like that it tries to auto-create the folder for me, but maybe there's an order-of-operations problem here?  It's been going for 20 minutes now, just sitting there.

Also, if the desired behavior is to auto-create the hdfs folders, this other setting needs to be updated to work the same way:

"yarn.resourcemanager.fs.state-store.uri": 'hdfs:///apps/yarn/rmstore'

Setting that just makes the resource manager crash until I can go in and create the folder in hdfs.

Here's the task output that's  hanging.  Advice is appreciated, but I have a feeling I'm just going to be opening bug reports here.
