Hi,
I've got a Spark Streaming driver job implemented and in it, I register a
streaming listener, like so:
JavaStreamingContext jssc = new JavaStreamingContext(sparkConf,
Durations.milliseconds(params.getBatchDurationMillis()));
jssc.addStreamingListener(new JobListener(jssc));
where JobListener is defined like so
private static class JobListener implements StreamingListener {
private JavaStreamingContext jssc;
JobListener(JavaStreamingContext jssc) {
this.jssc = jssc;
}
@Override
public void onBatchCompleted(StreamingListenerBatchCompleted
batchCompleted) {
System.out.println(">> Batch completed.");
jssc.stop(true);
System.out.println(">> The job has been stopped.");
}
........................
I do not seem to be seeing onBatchCompleted being triggered. Am I doing
something wrong?
In this particular case, I was trying to implement a bulk ingest type of
logic where the first batch is all we're interested in (reading out of a
Kafka topic with offset reset set to "smallest").
