Support for OpenJDK and Upgrade to CDH 6

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.ht...).

 

Thank you for your time in advance.

Re: Support for OpenJDK and Upgrade to CDH 6

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_upgrad...

- For CDH:

Thanks and hope this helps,

Li
