CDH with JDK 1.8

I currently have my CDH 5.9 cluster currently on JDK 1.7 and wanted to know if its safe to upgrade the hosts to JDK 1.8. Also, is it possible to have the Cloudera manager to be on JDK 1.7 while the cluster to be upgraded to JDK 1.8.

 

Thanks!

Re: CDH with JDK 1.8

CDH and Cloudera Manager requirements are mentioned here: https://www.cloudera.com/documentation/enterprise/release-notes/topics/rn_consolidated_pcm.html

 

"... Cloudera does not support mixed environments, all nodes in your cluster must be running the same major JDK version."

 

If I want to run the hosts of the cluster on JDK 8, can I still have CM running on JDK 7?

 

Thanks!

Re: CDH with JDK 1.8

Can anyone weigh in on the possibility of running the cluster hosts, except the cloudera manager host, on JDK 1.8?

 

Thanks!
