instances not being able to create registry paths on secure clusters</h3>
+<p>This feature requires the YARN Resource Manager to do the setup securely of

+<ol>
+<li>The RM must have the specific patch applied to do this. It is not in
+Apache Hadoop 2.6.0; it is in HDP-2.2.</li>

Instantiation fails, "TriggerClusterTeardownException: Unstable Cluster"</h3>
<p>Slider gives up if it cannot keep enough instances of a role running -or
more
precisely, if they keep failing. </p>
