Chris Douglas resolved HADOOP-4202.
-----------------------------------
Resolution: Later
I'll close this for now. If it continues to be a problem and can't wait for
HADOOP-3628, it can be reopened.
In what environment is this causing problems? Per (2), I'm having trouble
imagining how a correctly written TestCase would run into this.
