Github user HyukjinKwon commented on the issue: https://github.com/apache/spark/pull/22144 It does try to fix a backward compatibility issue. It is found later now but still it is true we found a breaking issue to fix. Broken backward compatibility that potentially affects a set of users (it at least looks blocking an external Hive UDF library repo) sounds like a blocker to me. Some of Hive compatibility issues are reported late because IMHO it's a bit complicated to follow (it requires to take a look for both Hive and Spark at least).
