Managing CDH and Managed Services

If you use Cloudera Manager to manage your cluster, configuring and managing your cluster, as well as individual services and hosts, uses a different paradigm than if you use CDH without Cloudera Manager. For this reason, many of these configuration tasks offer two different subtasks, one each for clusters managed by Cloudera Manager and one for clusters that do not use Cloudera Manager. Often, the tasks are not interchangeable. For instance, if you use Cloudera Manager, you cannot use standard Hadoop command-line utilities to start and stop services. Instead, you use Cloudera Manager to perform these tasks.
