Hi,

I'm currently CDH 5.14 with Spark2, which uses the Spark CDS 2.3 (release 4).
I plan on upgrading to Cloudera Version 6, which I know uses CDS 2.2. It's my understanding that before the upgrade I will need to remove Spark 2 via Cloduera Manager

"If you are using a CDS 2 minor version higher than the version of Spark 2 included in the CDH 6 release you are upgrading to (2.2 in CDH 6.0.0), you must remove your Spark 2 services from Cloudera Manager."
https://www.cloudera.com/documentation/enterprise/upgrade/topics/ug_spark_standalone.html#concept_al...

As part of the upgrade, Spark2 CDS 2.2 would be installed. At this point am I able to then re download the Service Descriptor for 2.3 (release 4) and upgrade to that?

Spark2 now comes bundled with CDH thus for CDH 6.0 you are tied to the Spark 2.2 release. You will not be able to install Spark 2.3 separately. Please be aware you are facing a transitional issue from separate Spark2 distribution to CDH distribution. Future CDH versions will update Spark2 releases accordingly to the latest versions, thus this situation would not appear anymore. If Spark 2.3 is a requirement we recommend to wait for the C6.1 release instead.
