CPU time vs real time

CPU time is hugely different form real time.

CPU time is how much time something spent on the CPUs, while real time is what you and I experience as humans.

Think about this: assume you have the same job running over the same data but on one 20 node cluster, then a 200 node cluster. Overall, the same amount of CPU time will be used on both clusters, but the 200 node cluster will run 10x faster in real time.

CPU time is a useful metric when you have a shared system with lots of jobs running on it at the same time.

CPU time

The CPU time you are seeing there is of the entire map phase and the entire reduce phase... not just the function itself.

This is kind of confusing terminology because you have the map function and reduce function, which are only a portion of the map phase and reduce phase.

This is the total CPU time across all of the nodes in the cluster.

The reduce

The reduce phase consists of: shuffle, sort, reduce, output.

The map

The map phase consists of: record reader, map, combiner, and partitioner.
