You can seamlessly upgrade a previous Cloudera Data Engineering service
version to a new version.
important
Upgrading Cloudera Data Engineering service supports endpoint
stability only when you are upgrading from 1.5.4 SP2 or earlier versions to
1.5.5 or 1.5.5 SP1. Endpoint stability enables you to access the Cloudera Data Engineering service of the new version with the original
endpoint. Thus, you can use the existing endpoints without changing
configurations at the application level. The Cloudera Data Engineering
service endpoint migration process lets you migrate your resources, jobs, job
run history, Spark jobs
logs,
and event logs from your old cluster to the new cluster.
If you are upgrading Cloudera Data Engineering to 1.5.5 SP2 or higher
versions, endpoint stability is not supported. This means that the links to your
Cloudera Data Engineering Service and Virtual Cluster will change
after the upgrade.
After upgrading Cloudera Data Engineering from 1.5.4 SP2 or earlier
versions to 1.5.5 or higher versions, the Cloudera Data Engineering
Services and Virtual Clusters that were created in the earlier versions does not
work in Cloudera Data Engineering 1.5.5 or higher versions. Cloudera does not recommend using the
old Cloudera Data Engineering Services and Virtual Clusters that were
created before the upgrade. Instead, create new Services and Virtual Clusters in
Cloudera Data Engineering 1.5.5 or higher version that you
upgraded to and use them.
After upgrading Cloudera Data Engineering , the upgraded Virtual
Cluster retains the same base OS images used in the source Virtual Cluster. This
ensures maximum compatibility, particularly for jobs that depend on specific
Python and Scala versions, such as Spark jobs. For example, if the source
Virtual Cluster uses a standard Red Hat image, the upgraded Virtual Cluster
retains that image type. The same applies to security-hardened images. No
automation path is supported from a standard Red Hat image to a
security-hardened image or the other way around.
Once you upgrade to Cloudera Data Engineering version 1.5.5 SP2 or higher, the
endpoints that you were using in the previous version are not supported.
