Hi all, As described in this https://issues.apache.org/jira/browse/FLINK-11720 ticket our elasticsearch 5.x connector does not work out of the box on some systems and requires a version bump. This also happens for our e2e. We cannot bump the version in es 5.x connector, because 5.x connector shares a common class with 2.x that uses an API that was replaced in 5.2.
Both versions are already long eol: https://www.elastic.co/support/eol I suggest to drop both connectors 5.x and 2.x. If it is too much to drop both of them, I would strongly suggest dropping at least 2.x connector and update the 5.x line to a working es client module. What do you think? Should we drop both versions? Drop only the 2.x connector? Or keep them both? Best, Dawid
