INFO

Available as of Datameer 10

The 'External Systems' tab provides the functionality to synchronize workbooks into Hive. Data duplication from Datameer to Hive is avoided. Datameer creates external tables in Hive, which refer to a kept sheet of a Datameer workbook. The external Hive tables are managed by Datameer.

Both of the extension points are relevant for the authentication to your Hive server. Authentication via Kerberos or via username and password is possible.
