If you switch from the Redhat UBI image to the security hardened image,
note that the updated component versions and libraries can impact the
Cloudera Data Engineering operation.
Cloudera
strongly recommends testing the new implementation in a non-production environment first.
For
backward compatibility, you can continue using the Redhat UBI image. The security hardened image
is the recommended image; however, note that it requires testing and validation.
For more
information, see Security hardened Spark image migration guide.
