Just call context.write multiple times

Subject: Query map reduce

I am writing a simple map reduce code in java. How can I get multiple key- value pairs as
output from a single mapper. If there is any preferred link for that, please let me know.
I tried using hash map for it but there exist some errors in the same. Can an object of output
collector emit multiple key value pairs ?
