Cache Shuffle Based Operation Before Sort

Caching shuffle RDD before the sort process improves system performance. SQL planner can be intelligent to cache join, aggregate or sort data frame before executing next sort process. For any sort process two job is created by spark, first one is responsible for producing range boundary for

Re: Do transformation functions on RDD invoke a Job [sc.runJob]?
