Subject [jira] [Created] (HIVE-9174) Enable queuing of HCatalog notification events in metastore DB

--------------------------------

             Summary: 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
            Assignee: 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.
