Description

I've also come around to agreeing with Jon Hsieh that we should have a test mode that somehow randomizes test order to catch issues where unit test cases are written with the assumption of a certain order. It should not be on by default but can be enabled when evaluating patches for commit that include new tests.

Case in point is HBASE-7581, which seems to be due to a new test added in HBASE-5498. The patch on HBASE-5498 tested out all green in local tests prior to commit.
