QUESTION

How can I set a maximum allowed execution time per task on Spark-YARN?

Asked 2021-Aug-24 at 08:26

I have a long-running PySpark Structured Streaming job, which reads a Kafka topic, does some processing and writes the result back to another Kafka topic. Our Kafka server runs on another cluster.

It's running fine but every few hours it freezes, even though in the web UI the YARN application still has status "running". After inspecting the logs, it seems due to some transient connectivity problem with the Kafka source. Indeed, all tasks of the problematic micro-batch have completed correctly, except one which shows:

I haven't found a solution to do it with YARN, but a workaround using a monitoring loop in the Pyspark driver. The loop will check status regularly and fail the streaming app if status hasn't been updated for 10 minutes

Infinite loop of Resetting offset and seeking for LATEST offset

As it turns out, this behaviour of seeking and resetting is perfectly desirable in case that one does not read to the topic from beginning, but from latest offset. The pipeline then only reads new data that gets sent to the Kafka topic whilst it is running and since no new data was sent, the infinite loop of seeking (new data) and resetting (to latest offset).

Bottom line, just read from beginning or send new data and the problem is solved.

kafka-consumer-groups command doesnt show LAG and CURRENT-OFFSET for spark structured streaming applications(consumers)

Asked 2021-Jan-22 at 19:18

I have a spark structured streaming application consuming from kafka, for this application I would like to monitor the consumer lag. I 'm using below command to check consumer lag. However I don't get the CURRENT-OFFSET and hence LAG is blank too. Is this expected ? It works for other python based consumers.

ANSWER

"However I don't get the CURRENT-OFFSET and hence LAG is blank too. Is this expected?"

Yes, this is the expected behavior as Spark Structured Streaming applications are not committing any offsets back to Kafka. Therefore, the current offset and the lag of this consumer group will not be stored in Kafka and you will see exactly the result of the consumer-groups tool what you have shown.

I have written a more comprehensive answer on Consumer Group and how Spark Structured Streaming applications manage Kafka offsets here.

Reading from the beginning of a Kafka Topic using Structured Streaming when query started

Asked 2020-Jul-11 at 21:34

im using structured streaming to read from the kafka topic, using spark 2.4 and scala 2.12

im using a checkpoint to make my query fault-tolerant.

however everytime i start the query it jumps to the current offset without reading the exisitng data before it connected onto the topic.

is there a config for the kafka stream im missing?

As clearly explained in the official documentation

Kafka’s own configurations can be set via DataStreamReader.option with kafka. prefix, e.g, stream.option("kafka.bootstrap.servers", "host:port").

You options are missing the prefix.
