Support for OpenJDK and Upgrade to CDH 6

Thrisha — Fri, 16 Sep 2022 14:01:39 GMT

Hello,

We currently have CDH 5.15.0 running in our environments and have a necessity to support OpenJDK. Does upgrading to CDH 6 help in supporting OpenJDK? If yes, can we directly upgrade from CDH 5.15.0 to CDH 6 or do we have to downgrade first to CDH 5.14 and then upgrade to CDH 6 ( documentation does not show direct upgrade from CDH 5.15 to CDH 6 https://www.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_install_upgrade_notes.html#topic_1_2).

Thank you for your time in advance.

Hi @Thrisha,

Based on the latest documentation:

https://www.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_java_requirements.html

OpenJDK 8 is supported in Cloudera Enterprise 6.1.0 and higher, as well as Cloudera Enterprise 5.16.1 and higher.

Also upgrade from Cloudera Enterprise 5.15 to 6.1 is supported. Based on your current version, you can use below two doc links to start with:

- For Cloudera Manager:

https://www.cloudera.com/documentation/enterprise/upgrade/topics/ug_cm_upgrade_before.html#cm_upgrade_before

- For CDH:

https://www.cloudera.com/documentation/enterprise/upgrade/topics/ug_cdh_upgrade_before.html#ug_cdh_upgrade_before

Thanks and hope this helps,
