Thanks a lot, Rong and Peter. AFAIK, there is a flink hcatalog connector introduced in FLINK-1466 <https://issues.apache.org/jira/browse/FLINK-1466> that is added by Fabian. And there is another JIRA in FLINK-1913 <https://issues.apache.org/jira/browse/FLINK-1913> to document the use of connector.
I think we can start with looking at the existing hcatalog connector, adding missing documentation, and come up with a proposal to evolve the Flink HCatalog integration with ExternalCatalog, and the SQL client to make it both useful both SQL and non-SQL scenarios. Given we already have the integration implemented in AthenaX <https://github.com/uber/AthenaX> internally, we can help drive and contribute back to the community.
