Hi, I want to know can I rerun the analytic installation on my server ironwood. master. In my server, the Analytic setup is all finished, and it’s working, but now I want to upgrade my Hadoop version in analytics. So can I run the analytic installation with the latest Hadoop version on my server?
Hadoop version upgrade is needed at my server coz a malware attack. My Hadoop version is 2.7.2 and I want to change 3.2.3. But I don’t know how to upgrade. So, I want to install again analytic installation on the server, whether it’s possible or not. Pls help me and give me advice.
