[jira] [Created] (GOBBLIN-1257) Fix the handling of collection field types during ORC schema up-conversion in compaction

Sudarshan Vasudevan created GOBBLIN-1257:
--------------------------------------------

             Summary: Fix the handling of collection field types during ORC schema up-conversion in compaction
                 Key: GOBBLIN-1257
                 URL: https://issues.apache.org/jira/browse/GOBBLIN-1257
             Project: Apache Gobblin
          Issue Type: Bug
          Components: gobblin-compaction
    Affects Versions: 0.15.0
            Reporter: Sudarshan Vasudevan
            Assignee: Issac Buenrostro
             Fix For: 0.16.0


Currently, on schema change while copying map/list entries from the original schema into the evolved schema, all the entries in the collection point to the same reference. This is inadvertently caused by re-using the same WritableComparable object for all the values.
