I think this should be agreed on the dev list and appropriate wording be added to indicate that these connectors are not supported by the Flink community. Also I notice that the license is not Apache. Also there is not associated Jira in the title.

If this is accepted you should include the Chinese version of this change.

I suggest following the note :
NOTE: The Flink community is still in the process of translating Chinese documentations, some documents may not have been translated yet. If the document you are updating is not translated yet, you can just copy the English changes to the Chinese document.
