Thank you. However, the 2 installations(2 versions) I am talking about are not connected in any way. I am not looking for a solution with a central management for two or more versions, if that is what my queries have led you to believe. Each of the installations is independent of the other. I will run the version that I prefer but at any time, I will only run one version. I will provide different directories(in the ambari configuration for data, logs etc, not the HDP libraries which would reside in their respective default locations) for each version. With this idea, are there any issues that might arise? The possible issue I can think of is the overwriting of files in the system directories in linux where commands like hadoop, hbase, mapreduce etc from the older installation may get overwritten by the newer one. Do you think there may be other issues too and any plausible solution for them? ... View more

@Geoffrey Shelton Okot Thank you. I probably did not specify one point clearly. I'll try to rephrase my question. I want to know if I can have 2 versions of existing in parallel and by that I do not mean upgrade. I want to know if I can install 2.6.5 for now and later in the future another fresh installation on 3.0.0 on the same cluster even if it means that I cannot have the services for both versions running in parallel (say to avoid port conflicts, resource constraint etc). Is this possible? I see that the OS/Java or other requirements to be more or less the same so far for both versions. ... View more

@Felix Albani. Thank you for the response. Are both the versions of both components compatible with the underlying components like Hadoop & HBase versions which are part of HDP 2.6.5 despite having huge changes between those versions? ... View more
