I am trying to find the HDF-HDP compatibility matrix. IS it published in any location.
Is HDF versions beyond 2.1 compatilbe with HDP 2.3.6 when installed on different nodes and with each of them having their own Ambari?
Just came across this as looking for something similar - FWIW given its an old post - you can find support matrix information via the Hortonworks Doc site.
e.g. go HDF Dataflow 3.1.1 documentation - you can toggle between releases using the drop down link to choose the release you're interested. Under each recent version you'll see a link for "Support Matrices". Embedded within that there will be a HDP Support Matrices which will have the info.
Note: the old (major) versions don't have support matrices listed but recent versions do (i.e. 3.x onwards)
