> Key: HIVE-14315
> URL: https://issues.apache.org/jira/browse/HIVE-14315
> Project: Hive
> Issue Type: New Feature
> Components: Statistics
> Affects Versions: 2.1.0
> Reporter: Chao Sun
> Assignee: Chao Sun
> Attachments: HIVE-14315.0.patch
>
>
> Currently only ORC supports {{analyze table ... compute statistics noscan}}
> (via HIVE-6578) where stats such as # of rows, raw datasize, etc., can be
> obtained via the footer. The similar functionality should be implemented on
> Parquet since it also has the info in the metadata.
