ATTACHMENT ID: 12932031 - PreCommit-HIVE-Build
> Change Parquet reader to read metadata on the task side
> -------------------------------------------------------
>
> Key: HIVE-15131
> URL: https://issues.apache.org/jira/browse/HIVE-15131
> Project: Hive
> Issue Type: Bug
> Components: Reader
> Reporter: Chao Sun
> Assignee: Adesh Kumar Rao
> Priority: Major
> Attachments: HIVE-15131.1.patch, HIVE-15131.2.patch
>
>
> Currently the {{ParquetRecordReaderWrapper}} still uses the {{readFooter}}
> API without filtering, which means it needs to read metadata about all row
> groups every time. This could some issues when input dataset is particularly
> big and has many columns.
> [Parquet-84|https://issues.apache.org/jira/browse/PARQUET-84] introduced
> another API which allows to do row group filtering on the task side. Hive
> should adopt this API.
