CDP 7.1.9 backwards compatibility

Alfa6 — Tue, 21 Apr 2026 06:29:33 GMT

Hi, we need to upgrade an old Cloudera CDP 7.1.1 installation to Cloudera CDP 7.1.9 version. The components we use are the following:

Apache Hadoop (Includes YARN and HDFS) ,Apache Hive, Apache Impala, Apache MapReduce, Apache ORC, Apache Parquet, Apache Spark 2, Apache Sqoop, Apache Tez, Hive on Tez, Apache Zookeeper.

For your knowledge, is the cdp 7.1.9 version backwards compatible with the cdp 7.1.1?

Thanks in advance.

@Alfa6 CDP 7.1.1 to 7.1.9 is not a supported upgrade path.

You can upgrade the cluster to CDP Private Cloud Base 7.1.9 from CDP 7.1.8/7.1.7 SP2/7.1.7

For more information on the supported upgrade paths, see Supported in-place upgrade paths.

Hi @ymprakash and thank you for your answer. My question is a little bit different. We'll follow the supported upgrade path upon to reach the CDP 7.1.9 release. In the meantime we would like to be sure that we will have not any regression about our software developed on CDP 7.1.1. So we asked you if you think that CDP 7.1.9 could be backwards compatible with CDP 7.1.1.

Thank you!

@Alfa6 Excuse me for the delayed update. I am catching up to speed here:

In the meantime we would like to be sure that we will have not any regression about our software developed on CDP 7.1.1.

I hope you did get a chance to review the Component Versions page on the CDP 7.1.1 vs. 7.1.9. If not already, Please do:
CDP 7.1.1 Components Version: https://docs.cloudera.com/runtime/7.1.1/release-notes/topics/rt-runtime-component-versions.html

CDP 7.1.9 Components Version: https://docs.cloudera.com/cdp-private-cloud-base/7.1.9/runtime-release-notes/topics/rt-pvc-runtime-component-versions.html

Additionally, Since you are concerned about the Backward compatibility, You may want to read the deprecation notices for 7.1.9 too: https://docs.cloudera.com/cdp-private-cloud-base/7.1.9/runtime-release-notes/topics/rt-pvc-deprecated.html

Let us know how you plan your CDP upgrade. We are here to help for the hassle-upgrade experience on your CDP!
