> URL: https://issues.apache.org/jira/browse/DRILL-3810
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - JSON, Storage - Other, Storage - Parquet,
> Storage - Text & CSV
> Reporter: Bhallamudi Venkata Siva Kamesh
> Assignee: Steven Phillips
>
> Filesystem Plugin supports multiple type of file formats like
> * json
> * avro
> * text (csv|psv|tsv)
> * parquet
> and can support any type of file formats.
> Among these file formats, some of the file formats are schema based like
> *avro* and *parquet* and some of them are schema less like *json*.
> For schema based file formats, Drill should have capability to validate the
> query against file schema, before start executing the query.
