Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0039]Kubernetes is an open source container cluster project, which provides an automated deployment, scalable, and manageable platform for application containers between host clusters. Based on Kubernetes, it is convenient to monitor, manage and maintain Docker containers. In this embodiment, the nodes formed in the built Hadoop cluster include a master node (Master node) and a slave node (Slave node), and one or more Docker containers run in the master node and the slave node. Each node is configured with a unique property (for...

Abstract

The invention provides a method for establishing a Hadoop cluster based on Kubernets, comprising the following steps: S1, a Manager node circularly listens to the configuration information of each node in the Hadoop cluster, and dynamically encapsulates the configuration information into a system file; The system files are updated to the nodes in the Hadoop cluster by mounting the shared files through the Kubernets API, S2, a management request initiated by a user to a Hadoop cluster is recieved, the node in the Hadoop cluster executes the update operation according to the management request and notifies the Manager node, and the Manager node receives the modification request sent by the node executing the update operation to update the configuration information, and modifies the system file according to the updated configuration information. The invention can realize the dynamic maintenance of the Hadoop cluster, and improves the high availability and the high expansibility of the Hadoop cluster.

Description

technical field [0001] The invention relates to the field of cloud computing container technology, in particular to an implementation method for building a Hadoop cluster based on Kubernetes. Background technique [0002] Kubernetes is an open source container cluster management project, which can provide an open source platform between host clusters that can be automatically deployed, scalable, and application containers can be operated. Kubernetes usually works in conjunction with the Docker container tool and integrates multiple host clusters running Docker containers. It is very convenient to use Kubernetes to manage Docker container clusters. It can not only dynamically monitor the status of containers, but also maintain and manage containers. [0003] Hadoop is a software platform for developing and operating large-scale data processing. The open source software framework implemented based on the JAVA language can be implemented in a distributed cluster composed of ...
