The issue is that the getTable() method is overridden to always enable readless increments for the dataset instance. However, getTableAdmin() does not do the same thing.
Thus we are testing readless increments with HBase tables that do have the readless increment coprocessor.
It is amazing that all tests pass. That means there is no test that test repeated increments. Also, this means that the code path in BufferingTable that test regular increments is not covered by the test.
We should test both cases.
