Embodiment Construction

[0051] The present invention is realized by relying on the HDFS distributed file sharing system based on the local area network, and the system includes two parts, a client end and a server end. The following will describe in detail with reference to the accompanying drawings.

[0052] According to the division of system functions, it is decided to use C / S architecture for realization. Such as figure 1 Shown:

[0053] Client: Use HTTP request to call the Webservice interface opened by the corresponding server to achieve the purpose of data processing. The client of the present invention uses the Android system as a basis to realize the functions of server-side interface calling and user input processing. The client calls the server-side interface in the form of HTTP request, and the format of the transmitted data is Json format data. The Android HTTP request framework okHttp is used as the basic development package, and the package realizes the writing of okHttpUtils. When...

Abstract

The invention discloses an HDFS distributed file sharing method based on a local area network. The method comprises the following steps that 1) an HDFS is deployed on the local area network, and one server is used as a host node, which is an applied monitoring server; other N servers are used as slave nodes, which are applied storage servers; and 2) on a server terminal, the host node divides a file into a plurality of blocks with a fixed size and the blocks are stored in different slave node storage servers, and each data block has 2-3 backups. In the invention, a community file sharing function of the HDFS in the local area network can be realized, a file uploading rate can be greatly increased and a flow rate is reduced.

Description

technical field [0001] The invention relates to a local area network-based HDFS distributed file sharing system, which belongs to the technical field of the Internet. Background technique [0002] In the context of the era of big data, cloud storage applications are becoming more and more widespread, such as Weiyun and Baidu Cloud Disk are relatively mature storage tools. However, due to the limitation of network bandwidth, it takes time and traffic to upload larger files, and at the same time, it is impossible to obtain the file sharing status of other users in time. When corresponding documents and materials are needed, they need to be obtained through relatively complicated ways. [0003] But to save files on a certain hardware device, data security depends on the hardware device. With the rapid development of cloud computing technology at home and abroad, HDFS-based technology has been widely used. [0004] The design concept of HDFS (Hadoop Distributed File System) is...
