Sample results

How to view sample results from your SQL queries.

Because Cloudera Streaming Analytics - Kubernetes Operator does not install Kafka, in the Cloudera SQL Stream Builder UI you are not able to see any rows from the Flink jobs. To see sampled results from your SQL queries, you need to have a Kafka cluster installed and accessible by both Cloudera SQL Stream Builder and Flink pods, and change ssbConfiguration to configure Cloudera SQL Stream Builder to use Kafka for data sampling:

ssbConfiguration:
  application.properties: |+
	kafka.enabled=true
	spring.kafka.bootstrap-servers=example-kafka:9092
	spring.kafka.jaas.enabled=false
	spring.kafka.properties.security.protocol=PLAINTEXT
