Ok. Let me check that. So if we pass Class there we could wrap it with the

> Add HBaseTableSource
> --------------------
>
> Key: FLINK-2168
> URL: https://issues.apache.org/jira/browse/FLINK-2168
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Affects Versions: 0.9
> Reporter: Fabian Hueske
> Assignee: ramkrishna.s.vasudevan
> Priority: Minor
> Labels: starter
>
> Add a {{HBaseTableSource}} to read data from a HBase table. The
> {{HBaseTableSource}} should implement the {{ProjectableTableSource}}
> (FLINK-3848) and {{FilterableTableSource}} (FLINK-3849) interfaces.
> The implementation can be based on Flink's {{TableInputFormat}}.
