Can Phoenix v4.4 utilize HBase namespaces?

Question

As we've been evaluating the use of Phoenix + HBase in HortonWorks 2.3, we came upon the conclusion that in the current bundled version of Phoenix, 4.4, that namespaces are not supported. The upstream JIRAs are confusing but it looks like Phoenix will not support namespaces + permissions until 4.7-4.8.

This is what we seen when enabling Phoenix on our system. The SYSTEM.* tables are Phoenix's. Ours are in the ns: namespace.

Version 1.1.2.2.3.6.0-3796, r2873b074585fce900c3f9592ae16fdd2d4d3a446, Thu Jun 23 16:29:31 UTC 2016

Questions

Does this sound like a correct conclusion? If so what are my options in terms of Phoenix?

• upgrade it within HW 2.3 (assuming this is not an option)?
• work around it somehow?
• Move Phoenix tables manually out of default NS into our applications? How?

You can upgrade Phoenix within HDP 2.3 by replacing the correct jar files in `/usr/hdp/......phoenix
