[Beginner] Kafka 0.11 header support in Spark Structured Streaming

[Karthik Jayaraman]

Hi all,

I am using Spark 2.2.1 Structured Streaming to read messages from Kafka. I 
would like to know how to access the Kafka headers programmatically ? Since the 
Kafka message header support is introduced in Kafka 0.11 
(https://issues.apache.org/jira/browse/KAFKA-4208 
<https://issues.apache.org/jira/browse/KAFKA-4208>), is it supported in Spark. 
? If yes, can anyone point me to an example ?
