You can use cloudera manager to manage all the services in your cloudera quickstart vm. Cloudera Manager is the admin tool that provides a nice UI for managing the services. You can check the health status, start, stop or restart any service with just few clicks.
By default, Cloudera Manager is disabled when you start the cloudera quickstart vm. To enable it you need to issue the following command on the terminal:
sudo /home/cloudera/cloudera-manager --force --express
It will take few minutes so as to start cloudera manager for you.
Now, to open cloudera manager you need to visit: http://quickstart.cloudera:7180
