> Randomly (once in 1000 runs in my VM), I get the following exception.
> Exception in thread "DelayedContainerManager" java.lang.ClassCastException:
> java.util.LinkedList cannot be cast to
> org.apache.hadoop.yarn.api.records.Priority
> at
> org.apache.tez.dag.app.rm.TezAMRMClientAsync$$EnhancerByMockitoWithCGLIB$$9c9a5aeb.getTopPriority(<generated>)

> It appears to be a bug in mockito when using RETURNS_DEEP_STUBS in unit
> tests. With mockito 1.10.8 version, this issue isn't cropping up. Currently
> tez uses mockito 1.9.5. Should we migrate to 1.10.8?
