[~jaltekruse], how do you think Drill should deal with this?
Drill could ignore unknown properties as [suggested
here|http://stackoverflow.com/questions/5455014/ignoring-new-fields-on-json-objects-using-jackson],
but any bad parameter is also ignored.

> Key: DRILL-4383
> URL: https://issues.apache.org/jira/browse/DRILL-4383
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - Other
> Reporter: Jason Altekruse
> Assignee: Jason Altekruse
> Fix For: 1.6.0
>
>
> A similar feature already exists in the Hive and Hbase plugins, it simply
> provides a key/value map for passing custom configuration options to the
> underlying storage system.
> This would be useful for the filesystem plugin to configure S3 without
> needing to create a core-site.xml file or restart Drill.
