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. If only to study the technology, and is a single machine, the memory is small, or it is recommended to install Apache native cluster to play, production is naturally cloudera cluster, unless there is a very powerful operation.I have 3 virtual machine nodes this time. Each gave 4G, if the host memory 8G, can ma
