Parallel computing is a generic thing: two or more processes run at the same time to cooperatively achieve a common task. Map reduce is parallel computing framework too but provides only two constructs:map and reduce. While this may seem too restrictive there are quite a bit of problems ranging from simple ETL (extract, transform, and load) to machine learning that can be expressed using maps and reduces. Map reduce frameworks such as Hadoop let’s the user worry about writing the logic for Map and Reduce tasks and takes care of doing the distribution of tasks. With built-in fault tolerance, this makes it great to come up with solutions to large scale data analytics problems easily. read less

If you think you are strong in finance and costing, I would suggest you a SAP FICO course which is definitely always in demand. if you have an experience as a end user on SAP PLM / Documentation etc, even a course on SAP PLM DMS should be good.
