Checking in to see if the RHEL8 support has been extended since. We're currently at a CDH 5.16.x.

We are planning an OS migration (CentOS6-7) on production environments with >200 hosts. For CM managed, parcel installs, I couldn't find knowledge base articles that show a rolling migration approach in place for an up and lift or blue-green migration of hadoop clusters. Is it supported? Blue-green migration would get quiet expensive for the period before we can decommission the old cluster.

No CDH roles on the CM server. This will be a new cluster with openjdk11 managed by a CM server with oracle jdk8. Sounds like that should work and be supported, keeping the cluster nodes and cluster settings consistent. Thanks, -Nithya

Hello Li, yes we plan to upgrade the CM version to 6.3 before we add a CDH6.3.x cluster. Will the CM server of oracle jdk8 support a new openjdk 11 cluster that it would need to manage? -Nithya

We plan on a blue-green migration of a CDH cluster from CentOS6-[7]; CDH 5.7-[6.3.3]; jdk 8-[openjdk11]. The cluster is managed by a CM that also manages several other clusters which will continue on jdk8. Is it supported to manage a cluster with nodes on jdk11 from a CM with jdk8?
