[jira] [Created] (TEZ-1684) upgrade mockio to latest release

Rajesh Balamohan created TEZ-1684:
-------------------------------------

             Summary: upgrade mockio to latest release
                 Key: TEZ-1684
                 URL: https://issues.apache.org/jira/browse/TEZ-1684
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rajesh Balamohan


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?
