Description

Running integration test against cluster I'm getting this on tip of branch-1:

It looks like this was broken by:

   5         HBASE-12404 Task 5 from parent: Replace internal HTable constructor use with
   6         HConnection#getTable (0.98, 0.99)

We used to create an HBaseAdmin internally with managed connection but we changed it to use the HTU's admin. In the patch we added check that there is a HTU cluster up and running – a mini cluster – but there won't be in the case of an IT test going against a cluster.
