Formatting the NameNode and Creating the /tmp Directory

When you add an HDFS service, the wizard automatically formats the NameNode and creates the /tmp directory on HDFS. If you quit the wizard or it does not finish, you can format the NameNode and create the /tmp directory outside the wizard by doing these steps:

  1. Stop the HDFS service if it is running. See Starting, Stopping, and Restarting Services.
  2. In the HDFS > Instances tab, click the NameNode role instance.
  3. Select Actions > Format.
  4. In the HDFS > Instances tab, click the NameNode role instance.
  5. Select Actions > Create /tmp Directory.
  6. Start the HDFS service.
