Hortonworks HDP

DSS supports HDP:

  • 3.0.0

  • 3.1.0

  • 3.1.4

  • 3.1.5

Support for HDP 2.6 is deprecated and will be removed in a future release.

HDP 3.1 support

Because of a bug in Hive (https://jira.apache.org/jira/browse/HIVE-20568), the Hive dataset

cannot be used when using HDP 3.1 if the Hive database name contains an underscore.

The JDBC driver of Hive will fail to properly consider that the table exists and DSS will consequently always complain that the dataset is not ready.

Limitations

  • Validation of Hive recipes with “UNION” or “UNION ALL” statements is not possible with HDP 3.X

Security

  • Connecting to secure clusters is fully supported

  • User Isolation Framework is supported with Ranger

DSS regular security and Ranger

When using DSS in regular security mode to connect to a secure cluster with Ranger, you need to add a Ranger HDFS rule, as described in Hive.

DSS User Isolation Framework and Ranger

When using DSS in User Isolation Framework mode to connect to a secure cluster with Ranger, you need to do some configuration adjustments, as described in Hive.

Migrating to HDP 3.X

If adding HDP 3.X support to an already-configured DSS instance, you must add the following lines to all of your Spark configurations:

spark.sql.hive.metastore.jars = builtin
spark.sql.hive.metastore.version =  1.2.1

See Spark configurations for more information on setting up Spark configurations
