> Follow-on from PHOENIX-3652:
> The fix provided in PHOENIX-3652 addressed the default situation where users would need ADMIN on the default HBase namespace. However, when {{phoenix.schema.isNamespaceMappingEnabled=true}} and Phoenix creates its system tables in the {{SYSTEM}} HBase namespace, unprivileged users (those lacking ADMIN on {{SYSTEM}}) still cannot connect to Phoenix.
> The root-cause is essentially the same: the code tries to fetch the {{NamespaceDescriptor}} for the {{SYSTEM}} namespace which requires the ADMIN permission.
