Alan Gates commented on HIVE-9174:

Thanks for catching the missing .sql files.  I agree, let's do that in a separate JIRA.

> HCatalog supports notifying listeners of events such as table creation, etc. using the
MetaStoreEventListener interface.  The only non-test implementation of this interface today
is NotificationListerner, which currently sends notifications via JMS.  This requires a JMS
service to be set up in the cluster.
> This JIRA proposes adding a new DbNotificationListener, that will store events directly
in the metastore, and allow users to access those events via HiveMetastoreClient.  This avoids
the need for a 3rd tool to install and manage when listening for events.
