If the data is too huge and is in S3, that'll be a lot of network traffic,
instead, if the data is available in HDFS (with proper replication
available) then it will be faster as most of the time, data will be
available as PROCESS_LOCAL/NODE_LOCAL to the executor.
Thanks

from local node gives considerable performance advantage over
