----------------------------------------------------------------
Just to bump this, as discussed in
[https://confluentcommunity.slack.com/archives/C48AHTCUQ/p1561063563237400]
this (and other related warnings) still happen in 2.2.1
The warning happens in Kafka Streams on several occasions:
* admin.retries because this is passed from streams itself to the admin client
* when trying to override a property for e.g. main.consumer.max.poll.records
* when trying to pass a property through the application properties to the
RocksDBConfigSetter (they are added automatically there, but also produce
warnings)
The first two pop up because the prefixes are stripped from the properties when
they are used but not handled in the comparison.
And the code does not filter out properties based on the prefix if they are not
even aimed at the receiver (e.g. admin.retries should not affect the producer).
The third would qualify for the "passthrough" approach mentioned in KAFKA-7509.
