> Currently, IcebergTable has an underlying HdfsTable that gives us headaches from time to time.
> We should identify the common data members and logic between IcebergTable and HdfsTable and put them into a helper class and both IcebergTable and HdfsTable would use that class internally.
> HdfsTable and IcebergTable have a common base interface FeFsTable, but we cannot put useful code there.
> OTOH, HdfsTable and IcebergTable both extend Table, so as an alternative option (to composition), it might be possible to put common code into a newly introduced common base class:
> {noformat}
>         Table
>           ^
>           |
>        FsTable (NEW)
>           ^
>          / \
>         /   \
> HdfsTable  IcebergTable{noformat}
