Problems solved by technology

However, the central node may not be able to receive the survival status information reported by the service node in time due to network delay, or may not be able to process the survival status information in time due to the overload of system resources. These situations may lead to the failure of the service node. The survival status information is lost, or the next update time is invalid, etc., then the central node may misjudge the survival status of the service node

Abstract

The embodiment of the present application provides a node processing method and device in a distributed system, the node includes a service node and a central node, and the method includes: obtaining the survival status information of the service node; obtaining the central node the current system information; use the survival state information and the current system information to determine whether the service node is abnormal; if the service node is abnormal, obtain the central state information of the central node; according to the center The state information processes the abnormal service node. The embodiment of the present application can integrate the status of the central node itself, and adaptively process abnormal service nodes, reduce the misjudgment of the service node status due to the central node's own problems, and reduce the probability of central node errors.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a node processing method in a distributed system and a node processing device in a distributed system. Background technique [0002] A distributed system is a system composed of one or more independent nodes that are geographically and physically dispersed, and the nodes include service nodes and central nodes. The central node can coordinate and deploy service nodes. These nodes are connected together to realize the sharing of resources, and the distributed system is equivalent to a unified whole. [0003] During the operation of the distributed system, the monitoring of the survival status of the service nodes is a very important link. The usual practice is that each service node in the distributed system sends survival status information to the central node at a predetermined period. After the central node receives the survival state information, it is used...
