Fixed
> Add Support for OAuth Enabled File Systems
> ------------------------------------------
>
> Key: DRILL-8364
> URL: https://issues.apache.org/jira/browse/DRILL-8364
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - File
> Affects Versions: 1.20.2
> Reporter: Charles Givre
> Assignee: Charles Givre
> Priority: Major
> Fix For: 2.0.0
>
>
> Currently Drill supports reading from file systems such as HDFS, S3 and
> others that use token based authentication. This PR extends Drill's plugin
> architecture so that Drill can connect with other file systems which use
> OAuth 2.0 for authentication.
> This PR also adds support for Drill to query Box.
