Non-Secure Impala with Secured Hive

[#1]

Hi Team,

We are in process on enabling TLS on HS2, I wanted to know/clarify if that happens will Impala be affected?

Impala is dependent on HMS and TLS is only limited to hive server 2, given that having TLS enabled on Hive and running Impala without it should be ok or do you see a scenario where this combination may not work?

Regards

This configuration does work.

It's an unusual and odd solution, though. If you are concerned enough with your data to enable TLS for HiveServer2, you should also enable TLS for Impala. Otherwise, your Hive data would still be exposed over the network when clients connect with Impala to run queries.

Regards,

André

Thanks for confirming that. We'll enable for Impala as well but after a week or so, but wanted to know if in the meantime it'd still work or not.
