2.2 - From Specific Nodes

Uninstalling the Big Data Protector from Specific Nodes

To uninstall Big Data Protector from selective nodes in the EMR cluster, use the node_uninstall.sh script from the <installation_directory>/cluster_utils/ directory.

Ensure that you uninstall the Big Data Protector from an account having full sudoer privileges.

  1. Login to the Lead node.

  2. Navigate to the <installation_directory>/cluster_utils/ directory.

  3. Create a new hosts file.

    For example, NEW_HOSTS_FILE. The NEW_HOSTS_FILE file contains the required nodes in the EMR cluster from where the Big Data Protector must be uninstalled.

  4. Add the nodes on the EMR cluster, from which the Big Data Protector needs to be uninstalled in the NEW_HOSTS_FILE.

  5. To remove the Big Data Protector from the nodes that are listed in the new hosts file, run the following command:

    ./node_uninstall.sh -c NEW_HOSTS_FILE

  6. Press ENTER.

    The prompt to enter the path of the Private Key file (.pem file) appears.

  7. Type the path of the private key file.

  8. Press ENTER.

    The Big Data Protector is uninstalled from the nodes in the EMR cluster, which are listed in the new hosts file.

  9. Check whether the nodes from which the Big Data Protector is uninstalled in Step 5 are removed from the CLUSTERLIST_FILE file.
