    could you change it to upper L?
    low l sometimes looks like 1

>             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}}.
