4.1. Adding a Hive Metastore Component
In Ambari Web, browse to Services > Hive.
In Service Actions, select the + Add Hive Metastore option.
Choose the host to install the additional Hive Metastore, then choose Confirm Add.
Ambari installs the component and reconfigures Hive to handle multiple Hive Metastore instances.

Important If you have Acid enabled in Hive, make sure that the Run Compactor setting is enabled (set to True) on only one Hive metastore host. To manage configuration settings for specific hosts using Ambari Web, select Services > Hive > Configs > Manage Config Groups, and set the Run Compactor setting to True on only one Hive Metastore host. For more information, see Using Host Config Groups.
