Subject [jira] [Created] (ATLAS-3148) Implement Hive Metastore hook for Atlas
Date Wed, 17 Apr 2019 23:18:00 GMT
Sarath Subramanian created ATLAS-3148:
-----------------------------------------

             Summary: Implement Hive Metastore hook for Atlas
                 Key: ATLAS-3148
                 URL: https://issues.apache.org/jira/browse/ATLAS-3148
             Project: Atlas
          Issue Type: New Feature
          Components:  atlas-core
    Affects Versions: 1.1.0
            Reporter: Sarath Subramanian
            Assignee: Sarath Subramanian
             Fix For: 2.0.0, trunk


Atlas has [hive hook|[http://atlas.apache.org/Hook-Hive.html]] which registers with HiveServer2
process to listen for create/update/delete operations and updates the metadata in Atlas.

If hive metastore is accessed using other clients like Impala shell, Hue or other JDBC/ODBC
client apps there is no way to capture the events in Atlas.

This Jira will create a new atlas hook for Hive Metastore - stores the metadata for Hive
tables and partitions in a relational database, and provides clients (including Hive) access
to this information using the metastore service API. 

This hook is registered as post-listener (hive.metastore.event.listeners) and DDL operations
are captured and send to atlas kafka topic for processing by Atlas server.

The following DDL operations are captured:
 * CreateDatabaseEvent
 * DropDatabaseEvent
 * AlterDatabaseEvent
 * CreateTableEvent
 * DropTableEvent
 * AlterTableEvent
