HIVE-20020, the hive-contrib JAR file was removed from the HiveServer2 classpath. With this change, the MultiDelimitSerDe is no longer included. This is fine, because MultiDelimitSerDe was a pain in that environment anyway. It was available to HiveServer2, and therefore would work with a limited set of queries (select * from table limit 1) but any other query on that table which launched a MapReduce project would fail because the hive-contrib JAR file was not sent out with the rest of the Hive JARs for MapReduce jobs.
Please bring MultiDelimitSerDe back into the fold so that it's available to users out of the box without having to install the hive-contrib JAR into the HiveServer2 auxiliary directory.
|Upgrade should update changed FQN for MultiDelimiterSerDe in HMS DB.||Resolved||
