[jira] [Created] (PARQUET-352) Add tags to "created by" metadata in the file footer

Ryan Blue created PARQUET-352:
---------------------------------

             Summary: Add tags to "created by" metadata in the file footer
                 Key: PARQUET-352
                 URL: https://issues.apache.org/jira/browse/PARQUET-352
             Project: Parquet
          Issue Type: Bug
          Components: parquet-mr
            Reporter: Ryan Blue


Hive has been writing timestamp (without time zone) data incorrectly by converting a timestamp with no time zone to UTC. There is no way to know that Hive definitely wrote the files, so it is difficult to add a recovery mechanism in the object model. Adding a tag for the object model to the "created by" metadata will allow us to detect situations like this in the future.
