Nodes with different Versions in a Cluster - is it possible

abhinav_joshi — Fri, 16 Sep 2022 13:03:52 GMT

Hi All , I have a Nifi Cluster containing 2 nodes which are on version 1.4. I have upgraded one of the nodes to 1.5 however this node doesnt get onto the cluster stating some wierd issue like connection refused. My question is - is this happening because the nodes are having incosistent versions. Cant we have nodes within a cluster having different versions ? @Peter Greiff @Bryan Bende @Matt Burgess

@Abhinav Joshi

HDF and HDP cluster does not support Heterogeneity of component versions as of now. Adding to it, difference in OS version across nodes in the cluster is not supported as well.
