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 ...
At present, email is still the main way to send information. However, when a large number of large files are sent, the e-mail server will soon feel the pressure, resulting in performance degradation and network bandwidth tension.

Aiming at the problem of low storage efficiency of small and medium files in cloud storage system based on HDFS, the paper designs a scheme of small and medium file in cloud storage System with sequential file technology. Using multidimensional attribute decision theory, the scheme by combining the indexes of reading file time, merging file time and saving memory space, we get the best way of merging small files, and can achieve the balance between the time consumed and the memory space saved; The system load forecasting algorithm based on AHP is designed to predict the system load. To achieve the goal of load balancing, the use of sequential file technology to merge small files. Experimental results show that ...
