The invention belongs to the technical field of computers, and relates to a resource preemption method and device, a computer readable storage medium and electronic equipment. The method comprises the following steps: acquiring queue parameters of a to-be-allocated resource queue and an allocatable resource queue, and determining the to-be-allocated resource queue to perform resource preemption on the allocatable resource queue according to the queue parameters; if the resource preemption is invalid preemption, resetting queue parameters of the to-be-allocated resource queue so as to perform resource preemption again; and if the resource preemption is effective preemption, determining a to-be-preempted container set according to the queue parameters of the allocable resource queue, so as to allocate resources in the to-be-preempted container set to the to-be-allocated resource queue. On one hand, the problem of idle resource waste caused by invalid preemption is avoided, a better resource preemption mode is provided, and the resource preemption efficiency is improved; and on the other hand, the problem of cyclic preemption is solved, the accuracy of determining the resource preemption of the large container is improved, and the effect of improving the resource preemption stability is further achieved.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a resource preemption method and resource preemption device, a computer-readable storage medium, and electronic equipment. Background technique [0002] A resource coordinator (Yet Another Resource Negotiator, Yarn for short) is a resource management system provided by the distributed computing infrastructure, which can allocate and schedule resources from the underlying distributed storage system to run upper-level applications. In Yarn's resource manager (Resource Manager), queues are created, and each queue can set the minimum quota and maximum quota of its own parent queue to improve the overall resource utilization of the cluster. When there is no task running in the queue, resources can be lent to other queues with high load through the scheduler; when the queue that lent resources receives a newly submitted application, the loaned resources can be recovered...
