stack commented on HBASE-12617:
-------------------------------
Before HBASE-12404, we were returning a new HBaseAdmin. We kept it around
while HTU was alive. It was made using managed connection under the wraps.
HBASE-12404 added to HTU a getConnection, a connection we keep around during
life of HTU so you can make tables and admins. We had inside in this new
method a check if HTU had a minicluster running. If not, we threw exception
("No connections allowed before minihbase cluster"). Seemed like good idea in
the HTU context. But the IT rig is calling through to here to get a connection
(Because IntegrationTestingUtility extends HBaseTestingUtility) even when test
against non-HTU minicluster.
Thanks for +1. Let me commit.
