apache hadoop cluster setup

Although I have installed a Cloudera CDH cluster (see http://www.cnblogs.com/pojishou/p/6267616.html for a tutorial), I ate too much memory and the given component version is not optional.

Although only with a single stand-alone version (standalone) of the pseudo-distributed cluster can also do experiments, but the sense of little meaning, but also in order to realistically restore the real production environment, after looking at some information, know that spark operation re
