Objective the goal of this document is to provide a learning starting point for users of the Hadoop Distributed File System (HDFS), where HDFS can be used as part of the Hadoop cluster or as a stand-alone distributed file system. Although HDFs is designed to work correctly in many environments, understanding how HDFS works can greatly help improve HDFS performance and error diagnosis on specific clusters. Overview HDFs is one of the most important distributed storage systems used in Hadoop applications. A HDFs cluster owner ...

I. Introduction We often see some similar in the program disassembled code 0 × 32118965 this address, the operating system called linear address, or virtual address.
