Big data cluster expansion method and device

Abstract

The invention provides a big data cluster expansion method and device. The big data cluster expansion method comprises the following steps: calling an Ambari tool for managing a cluster to be expandedto execute the following steps: modifying the configuration of at least one expansion node; installing an Ambari Agent on at least one expansion node; registering at least one expansion node to a to-be-expanded cluster; installing a component for at least one expansion node according to the to-be-expanded cluster; and calling Ansible Playbook, and completing the expansion operation of the to-be-expanded cluster according to the above steps and the node identifier of the at least one expansion node. According to the scheme, the cluster expansion difficulty can be reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a large data cluster expansion method and device. Background technique [0002] In recent years, with the rapid development of the Internet, mobile Internet, and the Internet of Things, various industries are generating a large amount of data all the time. Therefore, major Internet companies have built their own big data platforms to store these massive data, analyze and apply these data, and discover the value behind the data. [0003] However, with the continuous growth of the company's business scale and the number of users, the data storage capacity and access frequency of the Hadoop distributed file system cluster are increasing exponentially. The Ambari web management interface supports the expansion of the cluster, but the preparatory work of the expansion node still needs to be manually installed or configured. In particular, when expanding dozens or hundreds of machi...

AI Technical Summary

Problems solved by technology

The Ambari web management interface supports the expansion of the cluster, but the pre-preparation work for the expansion node still needs to be manually installed or configured

In particular, when expanding dozens or hundreds of machines at a time, it is very cumbersome to expand the capacity of the cluster, which increases the difficulty of cluster expansion
