Different ports in a Hadoop cluster environment?

0 votes
I am confused between the various ports at which various daemons / processes listens in a Hadoop cluster.

I see there are so many ports, which are:

1) 50070
2) 8088
3) 8042
4) 50075

Can anyone tell me what are the main port numbers which we should be aware of,
and what processes listens at those ports.
