Abstract

The invention provides a node state detection method and device in a distributed system and computer equipment, and relates to the technical field of computers. The method comprises the following steps: analyzing a heartbeat packet reported by each node in a currently associated task group to determine the current state of each node; when the current state of any node is abnormal heartbeat, sending an abnormal node detection request to other second detection services; receiving a detection result of any node returned by each second detection service; and under the condition that each detection result meets a preset condition, an abnormal node processing request is sent to the management control node, and the processing request comprises an identifier of any node. Therefore, under the condition that the first detection service judges that the heartbeat of the node is abnormal, the first detection service requests the other second detection services to verify the heartbeat abnormal node and then requests the management control node to process the abnormal node, so that the abnormal node existing in the distributed system can be timely and accurately found.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a method, device and computer equipment for detecting node status in a distributed system. Background technique [0002] A distributed system is a software system built on a computer network with a high degree of cohesion and transparency. A distributed system is composed of multiple work units. The work units in a distributed system are usually called nodes, and their specific forms can be software submodules, threads or processes, and subtask execution devices. Each node of the distributed system executes a part of subtasks respectively, and complex task execution requirements can be realized through the cooperative work among the nodes. If a node is abnormal, it will inevitably affect the task execution of the entire distributed system. Therefore, how to detect the state of nodes in distributed systems has become a key research direction. SUMMARY OF THE INV...
