class KafkaSink extends SparkListener

KafkaSink: write Spark metrics and application info in near real-time to Kafka stream use this mode to monitor Spark execution workload use for Grafana dashboard and analytics of job execution

How to use: attach the KafkaSink to a Spark Context using the extra listener infrastructure. Example: --conf spark.extraListeners=ch.cern.sparkmeasure.KafkaSink

Configuration for KafkaSink is handled with Spark conf parameters:

spark.sparkmeasure.kafkaBroker = Kafka broker endpoint URL example: --conf spark.sparkmeasure.kafkaBroker=kafka.your-site.com:9092 spark.sparkmeasure.kafkaTopic = Kafka topic example: --conf spark.sparkmeasure.kafkaTopic=sparkmeasure-stageinfo

This code depends on "kafka clients", you may need to add the dependency: --packages org.apache.kafka:kafka-clients:3.2.1

Output: each message contains the name, it is acknowledged as metrics name as well. Note: the amount of data generated is relatively small in most applications: O(number_of_stages)
