----------------------------------
Thanks for catching the missing .sql files. I agree, let's do that in a
separate JIRA.
> Enable queuing of HCatalog notification events in metastore DB
> --------------------------------------------------------------
>
> Key: HIVE-9174
> URL: https://issues.apache.org/jira/browse/HIVE-9174
> Project: Hive
> Issue Type: New Feature
> Components: HCatalog, Metastore
> Reporter: Alan Gates

>
> 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.
