Nodes with different Versions in a Cluster - is it possible

Expert Contributor

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

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.
