As we've been evaluating the use of Phoenix + HBase in HW 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.
Does this sound like a correct conclusion? If so what are my options in terms of Phoenix?
This is what we seen when enabling Phoenix on our system. The SYSTEM.* tables are Phoenix's. Ours are in the ns: namespace.

> Extended HDP services: Extended HDP services relates to the services that access the data stored in HDP including Hive, HBase, Storm, Spark and more. Extended services provide customers with the flexibility to uptake the innovation that is delivered on top of the common core, based on their own requirements and schedule. With Extended services, customers would be able to easily uptake the new functionality without causing any disruption to their core platform.
That's correct, idea is that you won't need to wait for major releases when innovative features like namespaces trickle down from community. We will ship non-core features more often than HDFS and YARN.
