How should I choose hadoop-core and hive-exec jar versions for Impala UDFs? What should they match in the target CDH installation?
For instance, hive-exec is now at version 3.1.0 but most examples I've seen use 0.13.x...

That is what I am asking. I have CDH 5.11, which reports:
Does this mean that I have to use hadoop-core-2.6.0 ? There isn't such version, as the max is hadoop-core-1.2.1.

We have a CDH Maven repository with the CDH version of things. CDH releases don't always align exactly with Apache releases - they may include additional bug fixes, features or may have non-production-ready features disabled.
I believe these are the docs for how to reference them via maven:
E.g. here is hadoop-core for 5.11.2: https://repository.cloudera.com/artifactory/cloudera-repos/org/apache/hadoop/hadoop-core/2.6.0-mr1-c...

I added cloudera repo to my gradle configuration and builds and functions run from Impala without problems.
