Hodoop namenode not starting

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

  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.
