Before You Uninstall
Verify prerequisites before you uninstall Big Data Management.
1. Verify that the Big Data Management administrator can run sudo commands.
2. If you are uninstalling Big Data Management in a cluster environment, configure the root user to use a passwordless Secure Shell (SSH) connection between the machine where you want to run the Big Data Management uninstall and all of the nodes where Big Data Management is installed.
3. If you are uninstalling Big Data Management in a cluster environment using the HadoopDataNodes file, verify that the HadoopDataNodes file contains the IP addresses or machine host names of each of the nodes in the Hadoop cluster from which you want to uninstall Big Data Management. The HadoopDataNodes file is located on the node from where you want to launch the Big Data Management installation. You must add one IP address or machine host name of the nodes in the Hadoop cluster for each line in the file.
