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.
Tip
Enable INFO
logging level for org.apache.spark.SparkContext logger to see what and when custom Spark listeners are registered.
