Why do we have these two in the separate forms? is MapRed different from MapReduce? Can you suggest me any source to clarify my doubt?

Firstly, we must learn that these are two separate APIs.

The first one which is MapRed is used in Hadoop version 1 which is

org.apache.hadoop.mapred

and the second was used in Hadoop version 2 where YARN was introduced and that version of API was called as MapReduce.
