Dear all, we are an education institute, we want to have a server for student projects in hadoop. we will be using all the hdp+HDF technologies. before we were planning to have two servers, one for HDP and one for HDF, but recently we found a document telling that we can install both in one server as well. https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.0.2/bk_installing-hdf-and-hdp/bk_installing-hdf-and-hdp.pdf so we plan to have one server to reduce the budget. we are planning to have the following, please correct us if something is not appropriate; CPU=16 core e5 xeon processor RAM=96GB HD=2 TB Network=10Gb bindwith. we will be installing the latest releases of hdp and hdf with centos operating system. please guide us with this. thank you.

Thank you Neeraj Sabharwal, yes, this is my fault not to go through the documentation first. i do first check documentations before touching any technology and i got this habbit from oracle. i dont know why in Hortonworks i skip documentations, may be it is new for me and a bit difficult to find the proper documentation... i dont know. but i promise, i will check them from now on. i really appriciate your kind replies and support. thank you so much.
