Spark source code is written in Scala but it does offer APIs in python, Scala and Java...Performance wise "Scala Spark" is very efficient though Data Scientists prefer "Py Spark" as Python offers more scientific libraries...So, it depends on your role...Developer aithey go with Scala Spark.. Spark can be treated as an updated version of mapreduce so underlying file storage system can still be HDFS/S3 buckets etc..You would not need Java but it is always recommended to at least lean the basics to understand the code...my 2 cents.. | ||
