Using requests-gssapi or unhacked requests kerberos should cause you to see the
following

This is what CALCITE-1922 attempts to fix. This would show up in failsafe

The output you posted looks strange as MIT should try to fallback to TCP or

> Add kerberos authentication to python-phoenixdb
> -----------------------------------------------
>
> Key: PHOENIX-4688
> URL: https://issues.apache.org/jira/browse/PHOENIX-4688
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Lev Bronshtein
> Priority: Minor
>
> In its current state python-phoenixdv does not support support kerberos
> authentication. Using a modern python http library such as requests or
> urllib it would be simple (if not trivial) to add this support.
