We see unit test failures in Jenkins that look like this:

java.lang.IllegalArgumentException: run queue not empty
	at org.apache.hbase.thirdparty.com.google.common.base.Preconditions.checkArgument(Preconditions.java:143)
	at org.apache.hadoop.hbase.procedure2.ProcedureExecutor.load(ProcedureExecutor.java:332)
	at org.apache.hadoop.hbase.procedure2.ProcedureExecutor.init(ProcedureExecutor.java:665)
	at org.apache.hadoop.hbase.procedure2.ProcedureTestingUtility.restart(ProcedureTestingUtility.java:132)
	at org.apache.hadoop.hbase.procedure2.ProcedureTestingUtility.restart(ProcedureTestingUtility.java:100)
	at org.apache.hadoop.hbase.master.procedure.MasterProcedureTestingUtility.restartMasterProcedureExecutor(MasterProcedureTestingUtility.java:85)
	at org.apache.hadoop.hbase.master.assignment.TestRollbackSCP.testFailAndRollback(TestRollbackSCP.java:180)

This isn't enough information to debug the situation. The test code in question looks reasonable enough – it clears the object for re-use between tests. However, somewhere between stop/clear/start we miss something. Add some toString implementations and dump the objects in the preconditions.

enough – it clears the object for re-use between tests. However, somewhere between
