Remove the Host Name from the Hadoop Slaves File

If the machine is still running, stop any Hadoop processes that are running on it before you continue.
To remove the host name from the Hadoop slaves file:
  1. Log on to the root node for the deployment as the root user or the user ID that installed the SAS High-Performance Deployment of Hadoop.
  2. Edit the /hadoop/hadoop-0.23.1/etc/hadoop/slaves file and delete the line that includes the host name to remove. Save and close the file.
    The path might be different for your deployment.
