When I use start-all.cmd, then datanode, resourcemanager, nodemanager are working properly but namenode is not working!

  • Welcome to SO! It's much better if you share your non-working code as a minimal reproducible example so that the proposed solution actually applies to your problem and can help future visitors with the same problem. Otherwise, there's a high likelihood that people will be tossing out random solutions that might not help you (or anyone else) much. See How to Ask and take the tour for more information on how to ask an on-topic question – Standin.Wolf Nov 04 '19 at 17:47

  1. Open cmd as administrator.
  2. Type and run stop-all.cmd
  3. Then run hadoop namenode –format
  4. Finally run start-all.cmd

Hope it will work for you.
