[jira] [Created] (ARROW-1436) PyArrow Timestamps written to Parquet as INT96 appear in Spark as 'bigint'

Lucas Pickup created ARROW-1436:
-----------------------------------

             Summary: PyArrow Timestamps written to Parquet as INT96 appear in Spark as 'bigint'
                 Key: ARROW-1436
                 URL: https://issues.apache.org/jira/browse/ARROW-1436
             Project: Apache Arrow
          Issue Type: Bug
          Components: Format, Python
    Affects Versions: 0.6.0
            Reporter: Lucas Pickup


When using the 'use_deprecated_int96_timestamps' option to write Parquet files compatible with Spark <2.2.0 (which doesn't support INT64 backed Timestamps) Spark identifies the Timestamp columns as BigInts. Some metadata may be missing.
