Abstract

The embodiment of the invention discloses a method for realizing file reading and/or writing, comprising the following steps: a first hadoop distributed file system (HDFS) client receives file reading information and/or file writing information sent by a client terminal, wherein the first HDFS client is the preset HDFS client corresponding to the client terminal in default; the first HDFS client interacts with a name server according to the file reading information and/or file writing information and acquires file node information sent by the name server; and the first HDFS client finishes the file reading and/or writing according to a data server corresponding to the file node information. The embodiment of the invention further discloses the data server. According to the invention, the file reading and writing based on HDFS can be simply and quickly realized, and the storage of huge data amount is finished; and the method can be conveniently operated on common computers, thereby greatly improving the system compatibility.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a method for realizing file reading and / or writing and a data server. Background technique [0002] Hadoop implements a distributed file system HDFS (Hadoop Distributed File System). HDFS has the characteristics of high fault tolerance and is designed to be deployed on low-cost hardware, and HDFS provides high transfer rates to access application data, suitable for applications with very large data sets. [0003] Such as figure 1 It shows a schematic structural diagram of a system for reading and writing files based on HDFS in the prior art. The system includes a client terminal, a name server (NameNode) and multiple data servers (DataNodes). The client terminal needs to be connected to the NameNode and all DataNodes , that is, it needs to interact with the NameNode and all DataNodes, and the client terminal must call the proprietary functions of HDFS to complete the rea...
