Hi all, I'm new to Spark so I'm sorry if the question is too vague. I'm currently trying to deploy a Spark cluster using YARN on an amazon EMR cluster. For the data storage I'm currently using S3 but would loading the data in HDFS from local node gives considerable performance advantage over loading from S3? Would the reduced traffic latency in data load affect the runtime largely, considering most of the computation is done in memory?
Thank you, Nisrina.
