The tooltip message should be aligned to the left (not center). 

Also, the following tooltip should be used for the parameters
* {{slider.user}} {code}User this view instance should run as. Specifying an empty value runs view as YARN service user (for example 'yarn'). Specifying '${username}' runs the view as the currently logged in user. Specifying any other value runs the view as that user. 

Administrators should check that the HDFS home folder for that user is created and accessible.{code}
* {{view.kerberos.principal}} - {code}Kerberos principal associated with this view. For example: ambari/_HOST@EXAMPLE.COM.

Administrators should make sure that HDFS service has the 'hadoop.proxyuser.[user].groups' and 'hadoop.proxyuser.[user].hosts' configs populated in 'core-site.xml'.{code}
* {{view.kerberos.principal.keytab}} - {code}Path to the Kerberos principal keytab used for view's user. For example: /etc/security/keytabs/ambari.headless.keytab

Administrators should make sure that HDFS service has the 'hadoop.proxyuser.[user].groups' and 'hadoop.proxyuser.[user].hosts' configs populated in 'core-site.xml'.{code}
