     This topic provides best practices for operating HAWQ, including recommendations for
stopping, starting and monitoring HAWQ.
    +## <a id="best_practice_config"></a>Best Practices for Configuring HAWQ Parameters
    +The HAWQ configuration guc/parameters are located in `$GPHOME/etc/hawq-site.xml`. This
configuration file resides on all HAWQ instances and can be modified either by the Ambari
interface or the command line. 
    +If you install and manage HAWQ using Ambari, use the Ambari interface for all configuration
changes. Do not use command line utilities such as `hawq config` to set or change HAWQ configuration
properties for Ambari-managed clusters. Configuration changes to `hawq-site.xml` made outside
the Ambari interface will be overwritten when you restart or reconfigure HAWQ using Ambari.
    +If you make changes using the command line interface, use a consistent `hawq-site.xml`
file to configure your entire cluster.
