Stamatis Zampetakis commented on HIVE-29063:
--------------------------------------------
The slowness seems to be introduced by the upgrade to JDK 17:
Before:
https://ci.hive.apache.org/blue/organizations/jenkins/hive-precommit/detail/master/2536/pipeline/642
After:
https://ci.hive.apache.org/blue/organizations/jenkins/hive-precommit/detail/master/2537/pipeline/661
Before the upgrade the javadoc generation was taking around ~1h and then it
jumped to 4hrs+. Not sure if we are missing some configuration toggle but we
should definitely do something about it cause it affects productivity,
resources and cloud cost.
