Leonid Ilyevsky commented on FLINK-13025:
-----------------------------------------

[~yanghua] I believe [~limbo] is using elasticsearch6 connector against 
Elasticsearch 7.x server. This is exactly what I am doing now. No compile 
errors, and no runtime errors if you add the 'type' element to every document.

However, as [~limbo] mentioned, the server will respond with a warning for 
every document, complaining about that 'type' element. Currently I simply 
suppress those warnings, but I suspect this still creates unwanted overhead and 
may affect performance.

Bottom line: we do need elasticsearch7 connector.
