Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Take the following existing environment as an example: an available system package yum source (both local and network); an available three-node hadoop cluster environment, and the host names of the three nodes are: node01.test .com, node02.test.com, node03.test.com.

[0014] Such as figure 1 As shown, the specific steps are described below.

[0015] In step S1, the installation package required by the kerberos service is installed, and related configuration files are modified to build a key distribution center (KDC) server. Specifically, all nodes install krb5-workstation, krb5-workstation and their dependent packages, and KDC nodes also install krb5-server.

[0016] In step S2, a new principal database is created for use by the hadoop cluster. Wherein, principal represents a basic entity (for example, a client or a server)...

Abstract

The invention discloses a method for establishing a hadoop identity authentication mechanism. The method comprises the following steps that a KDC server is established; a hafs principal, a mapred principal and an HTTP principal are established for each node in a hadoop cluster; a hafs.keytab file including the hdfs principals and the HTTP principals is established; a mapred.keytab file including the mapred principals and the HTTP principals is established. According to the method for establishing the hadoop identity authentication mechanism, the problems that in the prior art, hadoop access control is not safe, and cluster nodes can be simulated are solved.

Description

technical field [0001] The invention relates to the field of identity authentication, in particular to a method for constructing an identity authentication mechanism of hadoop. Background technique [0002] The era of big data provides many opportunities for Hadoop. Hadoop has been valued for its good scalability in massive data, efficient reading and writing and processing capabilities. However, behind many opportunities, Hadoop also faces many challenges. How to ensure the security of Hadoop has naturally become an unavoidable topic. Without access control, the data stored in it can be accessed at will or even perform misoperations such as deletion and modification, which will cause many potential risks. Therefore, Hadoop access control has become a very important requirement. [0003] In a Hadoop environment without authentication, authentication is not required when users interact with Hadoop Distributed File System (HDFS) or M / R. Malicious users can pretend to be rea...
