Grate video man. Lot of tutorials which don't cover how to actually use Hadoop after installation. Thanks for showing how to actually compile the java files. Keep up the good work.

Hi there,
I followed the tutorial but my program is stuck at
18/03/30 11:39:47 INFO mapreduce.Job: Running job: job_1522384963257_0001

I have set everything exactly as you told me to. Is there any solution ?
