> 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.
