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:
-
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.
-
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.
