Its great that you have added tests to check backward compatibility. Can
you add some comments to the test here, though. It is difficult to follow right
now exactly what this test is doing here.
> HBase namespaces surfaced in phoenix
> ------------------------------------
>
> Key: PHOENIX-1311
> URL: https://issues.apache.org/jira/browse/PHOENIX-1311
> Project: Phoenix
> Issue Type: New Feature
> Reporter: nicolas maillard
> Assignee: Ankit Singhal
> Priority: Minor
> Fix For: 4.8.0
>
> Attachments: PHOENIX-1311.docx, PHOENIX-1311_v1.patch,

> Hbase (HBASE-8015) has the concept of namespaces in the form of
> myNamespace:MyTable it would be great if Phoenix leveraged this feature to
> give a database like feature on top of the table.
> Maybe to stay close to Hbase it could also be a create DB:Table...
> or DB.Table which is a more standard annotation?
