Hi, I have a search application and want to monitor queries per second for it. I have Kafka at my backend which acts like a bus for messages. Whenever a search request is done I publish the nano time of the current system. I want to use Spark Streaming to aggregate such data but I am so new to it.
I wanted to follow that example: http://spark.apache.org/docs/latest/streaming-kafka-0-10-integration.html I've added that dependencies: <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-streaming-kafka-0-10_2.11</artifactId> <version>2.0.1</version> </dependency> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_2.10</artifactId> <version>2.0.1</version> </dependency> However I cannot see even Duration class at my dependencies. On the other hand given documentation is missing and when you click Java there is no code at tabs. Could you guide me how can I implement monitoring such a metric? Kind Regards, Furkan KAMACI
