<div class="block">:: DeveloperApi ::
A logger class to record runtime information for jobs in Spark. This class outputs one log file
for each Spark job, containing tasks start/stop and shuffle information. JobLogger is a subclass
of SparkListener, use addSparkListener to add JobLogger to a SparkContext after the SparkContext
is created. Note that each JobLogger only works for one SparkContext
<p>
NOTE: The functionality of this class is heavily stripped down to accommodate for a general
refactor of the SparkListener interface. In its place, the EventLoggingListener is introduced
to log application information as SparkListenerEvents. To enable this functionality, set
spark.eventLog.enabled to true.</div>
