Bikas Saha commented on TEZ-1684:
---------------------------------

We probably pull Hadoop version. Need to check if changing our own version separately can be an issue.

> 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>)
> 	at org.apache.tez.dag.app.rm.YarnTaskSchedulerService.assignReUsedContainerWithLocation(YarnTaskSchedulerService.java:1459)
> 	at org.apache.tez.dag.app.rm.YarnTaskSchedulerService.assignDelayedContainer(YarnTaskSchedulerService.java:660)
> 	at org.apache.tez.dag.app.rm.YarnTaskSchedulerService.access$700(YarnTaskSchedulerService.java:82)
> 	at org.apache.tez.dag.app.rm.YarnTaskSchedulerService$DelayedContainerManager.run(YarnTaskSchedulerService.java:1765)
> 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?
