Assignee: Nándor Kollár (was: Noémi Pap-Takács)
> Extract common code of IcebergTable and HdfsTable to a helper class
> -------------------------------------------------------------------
>
> Key: IMPALA-13738
> URL: https://issues.apache.org/jira/browse/IMPALA-13738
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Reporter: Zoltán Borók-Nagy
> Assignee: Nándor Kollár
> Priority: Major
> Labels: impala-iceberg
>
> 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}
