Hi, Was just curious. In Hadoop, You have a flexibilty that you can chose your class for SortComparator and GroupingComparator. I have figured out that there are functions like sortByKey and reduceByKey. But what if, I want to customize what part of key I want to use for sorting and which part for grouping(that which all records should go to single reducer corresponding to same key.)? Is there any way that could be achieved, wherein we can specify our own SortComparator and GroupingComparator.
Thanks and Regards, Archit Thakur.
