Job scheduling system and device for mixed nodes with strong and weak capabilities, and medium

Abstract

The application relates to a job scheduling system, equipment and medium for strong and weak ability mixed nodes, the system comprising: a coordinator module configured to maintain a cluster topology structure and execute a consistency election protocol; a scheduler module configured to generate a task dispatch strategy according to a global resource pool state and a job dependency relationship; an executor module configured to receive and execute a job instruction issued by the scheduler module; a trigger module configured to listen to an external event source and convert an event meeting a preset condition into a job scheduling request and send the job scheduling request to the scheduler module; and a communication abstraction layer configured to shield transmission differences of a bottom layer from an upper layer application according to attributes of a target node and a uniform resource identifier prefix. In the above embodiment of the application, the election protocol integrated with the node capability mask field completely solves the problem that a weak node is mistakenly selected as a master node, leading to instability of a cluster. The application effectively adapts to a narrowband and high-delay network environment and improves communication reliability in a weak network.
