    Description

      We are testing deploying an HDP 2.2. Cluster using ambari 2.0.0-rc2 running on ubuntu 12.04. I’ve been able to set up a cluster running HDFS, MapReduce2, YARN, Zookeeper, Knox, Ranger, and Ambari Metrics. When I shut down the whole cluster using Actions -> Stop All in Ambari, reboot the hosts, and then try to restart the cluster I see the error below restarting the Knox gateway. The directory /var/run/knox is indeed missing on the master host.

      Knox Gateway startup log:
