@Malrashed, If you are using Cloudera Runtime 7.1.9 then you can use either CDS 3.3 or CDS 3.5 Powered by Apache Spark as an add-on service. For more details, you can refer to this document. Please note, CDS 3.3 Powered by Apache Spark 3.3.x and CDS 3.5 Powered by Apache Spark 3.5.x are distributed as a parcel (Refer here for additional download details). There are no external Custom Service Descriptors (CSD) for Livy for Spark3 or Spark3 because they are already part of Cloudera Manager 7.11.3. In Cloudera Runtime 7.1.9, Spark 2 is the default. If you need to use Spark 3, it must be added as an add-on service. Note that Spark 2 is deprecated in Cloudera Runtime 7.1.9.

@moekraft Starting with Cloudera Runtime 7.3.x, Spark 3 is the default and integrated Spark version, and Spark 2 has been removed and is no longer supported. >> Does Spark still get installed separately or is it included with the base runtime? -- As a result, you do not need to install a separate Spark 3 parcel for CDP Private Cloud Base 7.3.x. The Spark 3 runtime is bundled within the Cloudera Runtime parcel itself so you won’t find a separate, compatible Spark 3 parcel in the support matrix or parcel repository for this version.  To proceed, simply use the Spark service that comes bundled with the Cloudera Runtime 7.3.x. After initial Cloudera Runtime 7.3.x installation, you can use the Add a Spark3 Service wizard to add and configure new service instances directly via Cloudera Manager >> Apparently Spark 3 is supported by 7.3.1 and Spark 3.5 by 7.3.1 SP1. -  Cloudera Runtime 7.3.1.100 CHF 1 bundled with Spark 3.4.x. Please refer the list of the official component versions for Cloudera Runtime 7.3.1.100 CHF 1 -  Cloudera Runtime 7.3.1.200 SP1 and latest bundled with Spark 3.5.x. Please refer the list of the official component versions for Cloudera Runtime 7.3.1.200 SP1. >> Should the support matrix be updated to reflect support for Spark 3?  - It's for CDS version support matrix, from Cloudera Runtime 7.3.x onwards you don't need CDS for Spark3, so you can refer the below release notes: https://docs.cloudera.com/cdp-private-cloud-base/7.3.1/private-release-notes/topics/rt-whats-new-spa... ...

Hello @QiDam    As stated by JD above, the CDE Service relies on Ozone Service on Base Cluster. If Ozone Service wasn't in Healthy State, the CDE Service enabling would fail with similar tracing as shared by you. We would recommend the following checks: Ensure Ozone Service is Up & Running on Base Cluster.  Create a new Environment & check CDE Service enabling on the new Environment.  If the above CDE Service enabling on new Environment is Successful, Reattempt the CDE Service enabling on the existing Environment. If the above Suggestion doesn't help, We would suggest engaging Support as any further troubleshooting would require sharing the Logs over the Public Community forum, which may have Customer's details.    We shall mark the Post as Resolved now. If you have any concerns, Feel free to Update the Post likewise.    Regards, Smarak ... View more
