> Project: HBase
> Issue Type: Task
> Components: proc-v2, test
> Reporter: Nick Dimiduk
> Assignee: Nick Dimiduk
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.6.0, 4.0.0-alpha-1, 3.0.0-beta-2, 2.5.9

> We see unit test failures in Jenkins that look like this:
> {noformat}
> java.lang.IllegalArgumentException: run queue not empty

> org.apache.hbase.thirdparty.com.google.common.base.Preconditions.checkArgument(Preconditions.java:143)

> {noformat}
> 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.
