Subject [jira] [Commented] (FLINK-9621) Warning when enabling partition discovery
Date Thu, 12 Jul 2018 09:40:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-9621?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16541390#comment-16541390
] 

Aljoscha Krettek commented on FLINK-9621:
-----------------------------------------

I think the problem is that we use the same properties for configuring both the Flink portion
and the connector and the Kafka portion. And Kafka issues warnings about the flink-specific
settings it doesn't know about.
