Zoltan Haindrich commented on HIVE-24394:
-----------------------------------------
[~johang] sorry for the long RTT - december is a bit more crowded (especially
now)
I see that you are after making things a little bit better - to debug queries
easier; what do you think about providing more details on the HS2 web interface?
I think the explain was already present there; I feel that is something we
really under-use - what do you think we really miss there; or its not really an
option for end users because its a web ui?
> Enable printing explain to console at query start

> Currently there is a hive.log.explain.output option that prints extended
> explain to log. While this is helpful for internal investigations, it limits
> the information that is available to users. So we should add options to make
> this print non-extended explain to console,. for general user consumption, to
> make it easier for users to debug queries and workflows without having to
> resubmit queries with explain.
