Q: If we set Replication factor 3 for a file, does it mean any computation will also take place 3 times?

No. Replication factor of 3 means that there are 3 copies of a file. But computation takes place only one the one copy of file. If the node on which first copy exists, does not respond then

 

computation will be done on second copy.
