i had faced the same question in an interview but did not able to answered ..now cleared ..but just extended one ..lets say i have only one data node which is able to store 1 replication(lets say that data node have 200 mb left) ..so what will happen to other replica if my replication factor is 3 ..will the job fail or something else .

With just one data node, it doesn't make any sense to have replication factor of 3. Hdfs will not store more than one copy.
