I would like to know how many people can use a single Hadoop cluster at one time? I am asking because I need to figure out whether or not a single 5 or 10 node cluster would be sufficient to host a class of 12 to 24 students.
Also, I am wondering if anyone could recommend whether the specifications each for the nodes on a high-end educational-level cluster should be the same as for any other production-level cluster ( ie. 64G-128G RAM, 24TB hard drive space, 8 cores, etc.). I believe that the dataset sizes that students would be using will range between 20MB minimum to about 0.500TB maximum, I imagine that we will ultimately be working on real problems and datasets, even if they are not exactly considered to be big data.
