Deploying CDH4 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 FileSystem (HDFS), and all services and daemons communicate over local TCP sockets for inter-process communication.
To deploy CDH4 in pseudo-distributed mode (and to install it if you have not already done so) follow the instructions in the CDH4 Quick Start Guide .
