SparkListenerInterface¶

SparkListenerInterface is an abstraction of event listeners (that SparkListenerBus notifies about scheduling events).

SparkListenerInterface is a way to intercept scheduling events from the Spark Scheduler that are emitted over the course of execution of a Spark application.

SparkListenerInterface is used heavily to manage communication between internal components in the distributed environment for a Spark application (e.g. web UI, event persistence for History Server, dynamic allocation of executors, keeping track of executors).

SparkListenerInterface can be registered in a Spark application using SparkContext.addSparkListener method or spark.extraListeners configuration property.
