Ravinder Matte updated SPARK-23294:
-----------------------------------
Affects Version/s: (was: 2.0.2)
2.2.1
> Spark Streaming + Rate source + Console Sink : Receiver MaxRate is violated
> ---------------------------------------------------------------------------
>
> Key: SPARK-23294
> URL: https://issues.apache.org/jira/browse/SPARK-23294
> Project: Spark
> Issue Type: Bug
> Components: DStreams
> Affects Versions: 2.2.1
> Reporter: Ravinder Matte
> Assignee: Takeshi Yamamuro
> Priority: Minor
> Labels: kinesis
> Fix For: 2.2.0
>
>
> I am calling spark-submit passing maxRate, I have a single kinesis receiver, and batches of 1s
> spark-submit --conf spark.streaming.receiver.maxRate=10 ....
> however a single batch can greatly exceed the stablished maxRate. i.e: Im getting 300 records.
> it looks like Kinesis is completely ignoring the spark.streaming.receiver.maxRate configuration.
> If you look inside KinesisReceiver.onStart, you see:
> val kinesisClientLibConfiguration =
> new KinesisClientLibConfiguration(checkpointAppName, streamName, awsCredProvider, workerId)
> .withKinesisEndpoint(endpointUrl)
> .withInitialPositionInStream(initialPositionInStream)
> .withTaskBackoffTimeMillis(500)
> .withRegionName(regionName)
> This constructor ends up calling another constructor which has a lot of default values for the configuration. One of those values is DEFAULT_MAX_RECORDS which is constantly set to 10,000 records.
