1. The introduction of the Hadoop Distributed File System (HDFS) is a distributed file system designed to be used on common hardware devices. It has many similarities to existing distributed file systems, but it is quite different from these file systems. HDFS is highly fault-tolerant and is designed to be deployed on inexpensive hardware. HDFS provides high throughput for application data and applies to large dataset applications. HDFs opens up some POSIX-required interfaces that allow streaming access to file system data. HDFS was originally for AP ...

Hadoop technology in telecom operators online log processing application architecture Fang Jianguo First, the telecom operators Internet log processing status Today, so popular in the mobile Internet, every day will produce a lot of Internet log, these Internet log due to the huge amount of data generated Can only be retained for 3 days, because of storage space and other reasons are discarded. At present, telecom operators may only have a lot of useful information on customer behavior missing from the analysis of customer behavior mainly based on CDRs (call logs). For example, two people with similar phone conversations may be completely different types of customers ...

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 ...
