Description

This task aims to remove the old file-based transform functionality, which consumes and produces csv/binary data and metadata files instead of the recently integrated frames. Overall, this allows us to significantly reduce the complexity of the code.

However, an open discussion point is the support of frame-based transform on MapReduce. The file-based transform supports MR whereas our frame-based transform does not.
