Adding a new NameNode

This topic lists the steps to add a new NameNode.

On the CES HDFS cluster, perform the following:
  1. Add the new NameNode to your CES HDFS cluster by following the steps in CES HDFS Administration section.
  2. Stop the new HDFS Transparency NameNode by running the following command on the new node:
    # /usr/lpp/mmfs/bin/mmces service stop HDFS
    You need to stop the HDFS Transparency NameNode because the Cloudera Manager can only manage the HDFS Transparency nodes when they are started using the Cloudera Manager.
On the Cloudera Manager GUI, perform the following:
  1. Click IBM Spectrum Scale > Instances > Add Role Instances to add the new NameNode.
  2. Restart all the services in the Cloudera Manager.
