This code creates an HBase mini-cluster and starts it.
Next, it creates a table called `MyTest` with one column family, `CF`.
A record is inserted, a Get is performed from the same table, and the
insertion is verified.
NOTE: Starting the mini-cluster takes about 20-30 seconds, but that should be
appropriate for integration testing.

Should we just remove this now?
