The test driver allows you to write sample input into your processing topology and validate its output. Note: Previously, I've written about using Kafka and Spark on Azure and Sentiment analysis on streaming data using Apache Spark and Cognitive Services. All examples include a producer and consumer that can connect to any Kafka cluster running on-premises or in Confluent Cloud. until that moment we had created jar files and now we'll install Kafka and MySQL. I had a scenario to read the JSON data from my Kafka topic, and by making use of Kafka 0.11 version I need to write Java code for streaming the JSON data present in the Kafka topic.My input is a Json Data containing arrays of Dictionaries. Spark Streaming integration with Kafka allows users to read messages from a single Kafka topic or multiple Kafka topics. This blog entry is part of a series called Stream Processing With Spring, Kafka, Spark and Cassandra. Kafka Streams are supported in Mac, Linux, as well as Windows operating systems.
