Example Embodiment

[0068]Next, the technical scheme in the present application embodiment will be described in the present application embodiment, and it is understood that the described embodiments are merely the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, one of ordinary skill in the art is in the scope of the present application without making creative labor premistence.

[0069] Currently, one kind of high-availability Kubernetes Flink on deployment scenario is: Start plurality Flink JobManager (job management node), based on the Kubernetes ConfigMap (configuration dictionary), when a failure in the main JobManager switched to the standby JobManager simultaneously on kubernetes.

[0070] However, this solution in the implementation process, we need to launch multiple JobManager can be achieved Flink on kubernetes highly available deployment on kubernetes, take up more resources.

[0071] To this end, the present applica...

Abstract

The invention provides a node management method and device, electronic equipment and a storage medium, and belongs to the technical field of big data. The method comprises the steps of monitoring a running state of a job management node in a running process of the job management node; when it is monitored that the job management node quits operation due to the fault, acquiring a target snapshot stored in the operation process of the job management node, wherein the target snapshot is used for storing intermediate data in the operation process of the job management node; and restarting the job management node based on the target snapshot. Namely, high-availability deployment of the Flink on the kubernetes can be realized only by running one job management node, and a plurality of job management nodes do not need to be run at the same time, so that server resources are saved.

Description

Technical field [0001] The present application relates to large technical field of data, particularly to a node management method, apparatus, electronic apparatus and a storage medium. Background technique [0002] Flink (Distributed streaming data flow engine) as a new generation of big data processing engine, with its powerful computing capabilities and advanced design concepts, to become the current hot technology framework, is valued by many Internet companies. kubernetes (container orchestration engine) is a popular container layout tools, combined with the docker (application container engine) technology, can provide a powerful cluster resource management functionality, one of the main cloud solution container. [0003] Currently, one kind of high-availability Kubernetes Flink on deployment scenario is: Start plurality Flink JobManager (job management node), based on the Kubernetes ConfigMap (configuration dictionary), when a failure in the main JobManager switched to the s...
