Abstract

The invention provides method and device for responding to an operation instruction in a distributive system, and aims at achieving relatively high operation efficiency and ensuring the reliability of the Hadoop group while updating the user authority and expanding the capacity of nodes. The method comprises the steps of determining all NameNode in the Hadoop system; polling the determined NameNode after receiving the operation instruction; implementing the operation instruction to the polled NameNode.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for responding to operation instructions in a distributed system. Background technique [0002] Hadoop is a distributed system infrastructure developed by the Apache Foundation. Users can develop distributed programs without knowing the underlying details of the distribution. Make full use of the power of the cluster for high-speed computing and storage. Hadoop implements a distributed file system (Hadoop Distributed File System), referred to as HDFS. HDFS has the characteristics of high fault tolerance and is designed to be deployed on low-cost (low-cost) hardware; and it provides high throughput (high throughput) to access application data, suitable for those with large data sets (largedata set )s application. HDFS relaxes the requirements of (relax) POSIX, and can access (streamingaccess) data in the file system in the form of streams. [0003] After...
