Who will setup multimode and single node modes?

0 votes
Hi guys. I am new to hadoop and I am learning by watching videos and from blogs. Almost every video or blog out there teaches how to setup single and multi mode clusters. My question is, in a company who does this setup? Does every engineer has to do this?

Cluster management is something that is generally taken care by hadoop admin but neither standalone nor pseudo distributed(single node) falls under cluster management(because it is used mainly for testing or development purpose) so this is a developer's part of the job just like you need eclipse installation to execute java codes.
