[jira] [Created] (PARQUET-347) Thrift projection does not handle new (optional) fields in requestedSchema

Alex Levenson created PARQUET-347:
-------------------------------------

             Summary: Thrift projection does not handle new (optional) fields in requestedSchema
                 Key: PARQUET-347
                 URL: https://issues.apache.org/jira/browse/PARQUET-347
             Project: Parquet
          Issue Type: Bug
          Components: parquet-mr
            Reporter: Alex Levenson


It should be valid to request an optional field that is not present in a file (it should be assumed to be null) but instead this throws eagerly in:
