HWC on CDP 7.3.1 with Spark 3.5

David_Ghazaleh — Tue, 21 Apr 2026 06:12:17 GMT

Hello.

I am on CDP CDH-7.3.1-1.cdh7.3.1.p400.67986116, using Spark 3.5.4.7.3.1.400-100 and no longer able to to find HWC classes under com.hortonworks.spark.sql.hive.llap.*.

Is HWC deprecated and/or unsupported on CDP 7.3.1+?

Thank you.

David.

Hello David,

I believe HWC is still supported on CDP 7.3.1. We can see the documentation for HWC in CDP 7.3.1.
-> https://docs.cloudera.com/cdp-private-cloud-base/7.3.1/integrating-hive-and-bi/topics/hive_hivewarehouseconnector_for_handling_apache_spark_data.html

And the HWC libraries are also available in the CDH parcels.

Please follow the below documentation to configure the HWC with CDP.

HWC libraries will be present in the CDH parcels.

Reference -

In 7.3.1 HWC is still supported.

Reference - https://docs.cloudera.com/cdp-private-cloud-base/7.3.1/integrating-hive-and-bi/topics/hive_hivewarehouseconnector_for_handling_apache_spark_data.html

Still could see HWC related classes under the package com.hortonworks.spark.sql.hive.llap.
