Eclipse or … This tutorial walks you through connecting your Spark application to Event Hubs for real-time streaming. EventLoggingListener is a private[spark] class in org.apache.spark.scheduler package. When Spark reads data, the read event is invoked twice - the first time after reading the first record and the second time after loading all the records. In other words, the read event listener is invoked with two values. The first time, the value of records read is one. SparkListener could be a source of interesting events, like: application start/end, job start/end, executor add/remove. The local listener is executed on the node that initiated the query. This is the source code of the Azure Event Hubs Connector for Apache Spark. To solve the above problems, we propose to get rid of the event queue and the single threaded event processor. Add the following line to build.sbt (the main configuration file for the sbt project) that adds the dependency on Apache Spark. The event queue is java.util.concurrent.LinkedBlockingQueue with capacity of 10000 SparkListenerEvent events. It makes a path to pass listener events to register spark listeners. SQLExecutionUIData is the data abstraction of SQLListener to describe SQL query executions. The Spark API, which saves data to a specified location, does not generate events in the Hive metastore so it is not supported by automatic metadata management. 通过实现这个类中的各种方法便可实现自定义的事件处理动作.
