    Hi @fhueske , 
    
    Regarding to the field type serialization, I think maybe we can provide 
default deserialization for basic types (int,long,String...) if users do use 
the `Bytes.toBytes(...)` to serialize the basic types. If not, users can ask 
this field to return raw bytes in this way:  `htableSchame.add("column_family", 
"qualifier", byte[].class)` and then use an user defined scalar function to 
deserialize the value.
    
    regarding to the rowkeys, I agree with you. It would be great if we can set 
scan range by WHERE clause. But FLINK-3849 (FilterableTableSource) is still a 
pending PR, I would suggest to break this issue into two. 1. add 
HBaseTableSource, provide access to HBase tables and support nested schema. 2. 
extend HBaseTableSource to support FilterableTableSource.

> 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}}.
