Installing CDH 5 on a Single Linux Node in Pseudo-distributed Mode

You can evaluate CDH 5 by quickly installing Apache Hadoop and CDH 5 components on a single Linux node in pseudo-distributed mode. In pseudo-distributed mode, Hadoop processing is distributed over all of the cores/processors on a single machine. Hadoop writes all files to the Hadoop Distributed File System (HDFS), and all services and daemons communicate over local TCP sockets for inter-process communication.
