According to the release page  Hive 2.3.3 works with Hadoop 2.x.y (not
3.x.y) so if you want to run with Hadoop 3.2.1 try a newer version.
Other than that the error looks like a classpath problem related with
guava. I guess you have one Guava version coming from Hive and another
I am nowhere near being an expert but just wanted to share my thoughts.
If I understand correctly you would like some syntactic sugar in Hive to
support partitioning as per Iceberg. I cannot tell if that's really useful
or not but from my point of view it doesn't seem a very good idea

There is now a PR  with various improvements over the last update. Feel
free to check it out and let me know what you think.

The hudson-jobadmin privilege can be granted by PMC chairs.
I don't know if there is any particular policy in Hive on who should have
this privilege so I guess you should request it from Ashutosh.

I put up a small project on GitHub  with Hive metastore dumps from
tpcds10tb/tpcds30tb (+partitioning) and some scripts to quickly spin up a
dockerized Postgres with those loaded.
Personally, I find it useful to check the plans of TPC-DS queries using the
usual qtest mechanism
The sooner we move away from the old system the better. It will also help
to detect and solve faster any kind of problems with the new approach if
there are more people using it.
Also it will be cool to have junit5 :D

+1 for failing fast starting with findbugs and eventually covering the
important points from checkstyle.

I am very happy working with the new system. Many thanks Zoltan!
I find the bot a good idea and I think its worth trying it out.
One thing to watch out is the case where contributors are willing to push
their work forward but there are no available reviewers to look to each
Personally, I would be also interested to see the results of these
experiments if they are available somewhere.
I didn't understand if the queries are failing at runtime or compile time.
Are the above errors the only ones that you're getting?

As far as it concerns query14 the problem is logged in HIVE-24167 .
There is also a PR  for reproducing the problem so it should be feasible
to find the offending commit with git bisect.
For queries 2 and 59, I am also able to reproduce the behavior that you
