Subject: Re: Enabling Tez sessions on HiveServer2

Hi Pala,

Can you share the settings you have used for those mentioned in the
document? Are you trying to use the tez session pools? As the document
mentions, you need to disable doAs to ensure usage of the session
pool. Also, the hive server 2 settings need to be in place at the time
of starting the server.

Regards
Vikram.
