Embodiment

[0142] The security optimization method proposed by the present invention is implemented as a single plug-in in a multi-cluster Hadoop system in a single-sign-on manner, and can be started by a SHELL device of the multi-cluster Hadoop system. The developed prototype system can be flexibly integrated into or offloaded from the multi-cluster Hadoop system according to the needs of users. The prototype system of the safety optimization method proposed by the present invention includes six main modules: a general module, a security module, a user management module, a CA node module, a master node module and a slave node module. Figure 5 The interaction between the various modules is shown. Each module provides specific functionality, among them:

[0143] (1) The general module is the function library of the security optimization method, which provides the required basic interfaces for other modules, including event listeners, event processors and random message generators, etc.;...

Abstract

The invention provides a public key algorithm and SSL (security socket layer) protocol based method of optimizing security of a multi-cluster Hadoop system. The method includes the steps of authenticating identity of a user when the user logs in to a master node; allowing the master node to submit a request to a CA (certificate authority) server to acquire a proxy certificate; allowing the master node to create a slave node list and determine identity of the master node; allowing bidirectional authentication between the master node and slave nodes; allowing the multi-cluster Hadoop system to execute a task submitted by the user; stopping the user from submitting tasks. The method has the advantages that user authentication and network attack protection are effectively achieved for the Hadoop system running across multiple cluster environments, the defect of the original security mechanism of the single-cluster Hadoop system running in the multiple cluster environments is made up, and the network attack protection with the original security mechanism of the single-cluster Hadoop system forms complete security protection for the multi-cluster Hadoop system.

Description

technical field [0001] The invention relates to an optimization method, in particular to a multi-cluster Hadoop system security optimization method based on a public key algorithm and an SSL protocol. Background technique [0002] Hadoop system is an effective tool for big data processing. The early Hadoop system mainly ran in a single cluster environment, and later versions began to support running in multiple cluster environments. A multi-cluster Hadoop system is an extended version that runs across multiple cluster environments, such as figure 1 shown. JobTracker is the main server of the MapReduce framework, responsible for managing the control flow of the MapReduce framework to execute jobs, monitoring the health status of all executing tasks, detecting and rescheduling failed tasks until all tasks of a job are completed. The JobTracker receives new jobs from its user side, divides the jobs into smaller tasks and sends them to the TaskTracker. TaskTracker is the pow...
