In Beam 2.9.0, this check was made: https://github.com/apache/beam/blob/2ba00576e3a708bb961a3c64a2241d9ab32ab5b3/sdks/java/io/kafka/src/main/java/org/apache/beam/sdk/io/kafka/KafkaRecordCoder.java#L132
However this logic was removed in 2.10+ in the newer ProducerRecordCoder class: https://github.com/apache/beam/blob/release-2.10.0/sdks/java/io/kafka/src/main/java/org/apache/beam/sdk/io/kafka/ProducerRecordCoder.java#L137 We are attempting to use Beam 2.10 with kafka 0.10.2.1; this is advertised as supported here: https://beam.apache.org/releases/javadoc/2.10.0/org/apache/beam/sdk/io/kafka/KafkaIO.html However we are experiencing issues with the `headers` method call mentioned above. Is there a way around this? CONFIDENTIALITY NOTICE This message and any included attachments are from Cerner Corporation and are intended only for the addressee.
