[jira] [Created] (HIVE-20059) Hive streaming should try shade prefix unconditionally on exception

Prasanth Jayachandran created HIVE-20059:
--------------------------------------------

             Summary: Hive streaming should try shade prefix unconditionally on exception
                 Key: HIVE-20059
                 URL: https://issues.apache.org/jira/browse/HIVE-20059
             Project: Hive
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 3.1.0, 4.0.0, 3.2.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran
         Attachments: HIVE-20059.1.patch

AbstractRecordWriter tries hive.classloader.shade.prefix on ClassNotFoundException but there are instances where OrcOutputFormat from old hive version gets loaded resulting in ClassCastException. I think we should try shadeprefix when defined and when any exception is thrown.
