Zhaobo Yu created SPARK-25721:
---------------------------------
Summary: maxRate configuration not being used in Kinesis receiver
Key: SPARK-25721
URL: https://issues.apache.org/jira/browse/SPARK-25721
Project: Spark
Issue Type: Bug
Components: DStreams
Affects Versions: 2.2.0
Reporter: Zhaobo Yu
In the onStart() function of KinesisReceiver class, the
KinesisClientLibConfiguration object is initialized in the following way,
val kinesisClientLibConfiguration = new KinesisClientLibConfiguration(
checkpointAppName,
streamName,
kinesisProvider,
dynamoDBCreds.map(_.provider).getOrElse(kinesisProvider),
cloudWatchCreds.map(_.provider).getOrElse(kinesisProvider),
workerId)
.withKinesisEndpoint(endpointUrl)
.withInitialPositionInStream(initialPositionInStream)
.withTaskBackoffTimeMillis(500)
.withRegionName(regionName)
As you can see there is no withMaxRecords() in initialization, so
KinesisClientLibConfiguration will set it to 10000 by default since it has been
hard coded as this way,
public static final int DEFAULT_MAX_RECORDS = 10000;
In such a case, the receiver will not fulfill any maxRate setting we set, worse
still, it will cause ProvisionedThroughputExceededException from Kinesis,
especially when we restart the streaming application.
