Description

I'm trying to consume kinesis stream via spark streaming and amazon KCL lib.

Streaming job gets stuck at processing as so

on as it gets the first batch of non zero records.

I'm getting json data in my kinesis stream and here's what I'm trying to achieve:

Get Dstream[ArrayByte] > convert to Dstream[String] > RDD > load as json to create dataframe and perform transformations.

 

Similar error links:

https://stackoverflow.com/questions/40225135/spark-streaming-kafka-job-stuck-in-processing-stage

I'm running the job in emr-5.8.0 with enough number of cores and executors but still the job gets stuck in processing stage and build a huge pile of queued batches over time.

Not able to process even a single record.

 

Here's the code I'm using:

 

 

val numStreams=2
val sparkStreamingBatchInterval=10
val kinesisCheckpointInterval=5
 
val kinesisStreams = (0 until kinesisConfig("numStreams").toInt).map { i =>
 KinesisInputDStream.builder
 .streamingContext(ssc)
 .endpointUrl(kinesisConfig("endpointUrl"))
 .regionName(kinesisConfig("regionName"))
 .streamName(kinesisConfig("streamName"))
 .initialPositionInStream(InitialPositionInStream.LATEST)
 .checkpointAppName(kinesisConfig("appName"))
 .checkpointInterval(Seconds(kinesisConfig("kinesisCheckpointInterval").toInt))
 .storageLevel(StorageLevel.MEMORY_AND_DISK_2)
 .kinesisCredentials(awsCredentials.build())
 .build()
}
val unionStreams = ssc.union(kinesisStreams)

val lines = unionStreams.flatMap(byteArray => new String(byteArray).split(" "))
lines.print(2)

lines.foreachRDD(rdd => {
 if
 (!rdd.partitions.isEmpty){
 println("New records found\nmetrics count in the batch: %s".format(rdd.count())) //works
 println("performing transformations")
 rdd.saveAsTextFile("path")//works
 import sparkSession.implicits._
 println(rdd.toString()) //not working
 val records = rdd.toDF("records") //not working
 println(records.take(2)) //not working
 println(records.count()) //not working
 }
 else
 println("No new record found")
})
