Michael Armbrust updated SPARK-6774:
------------------------------------
Target Version/s: 1.6.0 (was: 1.5.0)
> Implement Parquet complex types backwards-compatiblity rules
> ------------------------------------------------------------
>
> Key: SPARK-6774
> URL: https://issues.apache.org/jira/browse/SPARK-6774
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.0.0, 1.1.1, 1.2.1, 1.3.0
> Reporter: Cheng Lian
> Priority: Critical
>
> [Parquet format PR
> #17|https://github.com/apache/incubator-parquet-format/pull/17] standardized
> representation of Parquet complex types and listed backwards-compatibility
> rules. Spark SQL should implement these compatibility rules to improve
> interoperatability.
> Before, Spark SQL is only compatible with parquet-avro, parquet-hive, and
> Impala. And it's done in an error prone ad-hoc way, because Parquet format
> spec didn't explicitly specify complex type structures at the time Spark SQL
> Parquet support was firstly authored. After fixing this issue, we are
> expected to be compatible with most (if not all) systems that generated
> Parquet data in a systematic way by conforming to Parquet format spec and
> implementing all backwards-compatibility rules.
