Butao Zhang commented on HIVE-29063:
------------------------------------
It seems that if building with JDK 21, the execution time of javadoc
generation can be reduced to ~1h.
https://github.com/apache/hive/pull/5880
https://ci.hive.apache.org/blue/organizations/jenkins/hive-precommit/detail/PR-5880/13/pipeline/477
But i am sure if this issue is related the JDK. We can check more CI logs on
the master branch to find some clues.
