Problems solved by technology
However, once the master service node or the determined slave service node fails, it may cause the received tasks to be executed to be put on hold and cannot be executed in time
Therefore, the current distributed task execution system has a single point of failure risk and cannot guarantee the reliability of task execution

The invention discloses an electronic device, a distributed task scheduling method and a storage medium. The method comprises the steps that request information is sent to all service nodes in a predetermined server cluster in real time or at fixed time; in a preset time threshold, whether response data returned by all the service nodes is received is determined; if it is determined that a certainservice node does not return response data in the preset time threshold, whether the service node is a master service node is determined; if it is determined that the service node is the master service node, an instruction for reselecting a master service node is sent to all the service nodes; and if it is determined that the service node is a slave service node, an instruction for reallocating ato-be-executed task of the slave service node to other service nodes is sent to the master service node. In this way, a single-point fault of a distributed system can be solved, and the reliability of task execution can be improved.
Description
technical field [0001] The invention relates to the field of computer processing, in particular to an electronic device, a distributed task scheduling method and a storage medium. Background technique [0002] Distributed task scheduling refers to assigning multiple tasks divided by an application or business to multiple servers in a server cluster for processing. Distributed task scheduling can solve the problem of insufficient resources of a single server and achieve the purpose of large-scale data computing. [0003] At present, distributed task scheduling is usually implemented using Zookeeper technology. The principle of Zookeeper is to send the received tasks in parallel to the determined From the service nodes (other servers in the server cluster), the parallel execution of tasks can be realized, and the speed of task execution can be improved. However, once the master service node or the determined slave service node fails, the received tasks to be executed may be ...
