>                 URL: https://issues.apache.org/jira/browse/DRILL-4364
>             Project: Apache Drill
>          Issue Type: New Feature

> Support querying of metadata in various image formats. This plugin leverages [metadata-extractor|https://github.com/drewnoakes/metadata-extractor]. This plugin is especially useful when querying on a large number of image files stored in a distributed file system without building metadata repository in advance.
> This plugin supports the following file formats.
> * JPEG, TIFF, WebP, PSD, PNG, BMP, GIF, ICO, PCX
> * Camera Raw: NEF (Nikon), CR2 (Canon), ORF (Olympus), ARW (Sony), RW2 (Panasonic), RWL (Leica), SRW (Samsung)
> This plugin enables to read the following metadata.
> * Exif, IPTC, XMP, JFIF / JFXX, ICC Profiles, Photoshop fields, WebP properties, PNG properties, BMP properties, GIF properties, ICO properties, PCX properties
> Since each type of metadata has a different set of fields, the plugin returns a set of commonly-used fields such as the image width, height and bits per pixels for ease of use.
> *Examples:*
> Querying on a JPEG file with the property descriptive: true
> {noformat}
> 0: jdbc:drill:zk=local> select * from dfs.`4349313028_f69ffa0257_o.jpg`;
