Spark 2.3 with Cloduera Version 6?

New Contributor

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.

Thank you for the claftiaftion.  Saved me a world of pain.

it's not very clear from the "Upgrading Spark" page that you cannot complete the upgrade when using version 6.

Thanks again.

We also like to have Spark 2.3 with CDH6, is it scheduled for CDH 6.1?

 

Thx,

Michel

Expert Contributor
Yes CDH 6.1 will have a Spark2 version upgrade.

New Contributor

Ok thanks. Any delivery expectation for 6.1?

It will be release within the regular schedule. If you need exact dates then please contact your Cloudera sales representative for more details.

This same issue is still present on CDH 6.1. 

Expert Contributor

Not exactly, this is not an issue at all but expected. It is what the error message says, the Spark 2.3 service is now (in C6) provided by the CDH parcel. There is no separate Spark2 parcel anymore, and you need to uninstall the Spark 2 parcel as advised in the doc chapter Migrating Apache Spark Before Upgrading to CDH 6
