The parallelize operation accepts as input a data structure in memory. When you call it, you are necessarily operating In the memory space of the driver since that is where user code executes. Until you have an RDD, you can't really operate in a distributed way.
If your files are stores in a distributed file system such as HDFS then you can create an RDD from those directly with sc.textFile(...).

Is it possible to do this in worker process for the sake of scalability? best /Shahab ________________________________________________________ The information contained in this e-mail is confidential and/or proprietary to Capital One and/or its affiliates and may only be used solely in performance of work or services for Capital One.
