really talented candidate

[@vedhh7727]

To reduce the shuffling, we can use reduce by key,
In general narrow transformation to be used , if an unavoidable wide transformation like a join, group By, distinct is there, we can filter the data first and then do the wide transformation in order to minimize the unwanted data.
So lesser records will be shuffled.
