Goal: Determine whether Phoenix handles Kerberos ticket renewal automatically for queries that exceed the default ticket lifetime.

Phoenix delegates authentication to the HBase security layer.
The HBase client can renew tickets if a renewal interval is configured, but Phoenix does not expose a setting to control this behavior.
Ticket lifetimes vary (e.g., 10 minutes in test clusters) and long‑running analytical queries may exceed them.

Does the HBase client automatically renew Kerberos tickets during a Phoenix query when renewal is enabled? If not, what mechanisms can prevent query failure due to expired tickets? Is there a way for Phoenix to propagate renewal settings to the underlying HBase client?
