Mike Drob commented on HBASE-17922:
-----------------------------------
tl;dr - either fix this test by applying the patch I have posted, or we can
also fix it by switching to HBaseTestingUtility.createLocalHTU. Both will work
around the MiniDFSCluster integration issues.
It's a bug somewhere in the stack for sure, but it's not something that will
get hit in operations unless people are trying to start and stop mini dfs
multiple times before their first use of hbase. I don't think this is impactful
to usability for folks.
