HeartSaVioR commented on issue #26632: [SPARK-29993][SS]Avoid continuous warn log in get record and offset from Kafka URL: https://github.com/apache/spark/pull/26632#issuecomment-558998748 KAFKA-1894 will not be resolved with just a version upgrade, as it was closed with KIP-266 as a solution. It requires to change the calls of Kafka API as non-blocking version (Having `Duration` as parameter), which we still don't migrate. We still call `poll()` with `long` parameter. When we migrate we should take the side effect into account that the semantic of timeout is changing - it will include the duration of fetching metadata as well. End users need to set bigger value of timeout, or we should add artificial value to given timeout.
