Re: Spark Streaming Shuffle to Disk

UpdateStateByKey and your batch data could be filling up your executor memory and hence it might be hitting the disk, you can verify it by looking at the memory footprint while your job is running. Looking at the executor logs will also give you a better understanding of whats going on. Thanks Bes
