Abstract

The invention discloses a method and device for executing a computing task, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: sending a calculation instruction to a main node, the calculation instruction carrying a calculation task, and receiving original data returned by the main node and generated by executing the calculation task; if it is monitored that the master node cannot execute the calculation task, selecting a new master node from slave nodes according to a preset rule; and sending a new calculation instruction to the new main node, the new calculation instruction carrying the original data, and receiving the original data returned by the new main node and generated by continuously executing the calculation taskaccording to the original data. According to the embodiment, the high-performance advantage and the high availability of the main node are ensured at the same time.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for performing computing tasks. Background technique [0002] Spark is a computing engine. For Spark clusters, the deployment method is mainly Spark on Yarn, and the Spark on Yarn deployment method is divided into two modes: Cluster (cluster) mode and Client (client) mode. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the Spark on YarnClient mode has a single point of failure problem and does not have high availability; while the Spark on Yarn Cluster mode executes computing tasks by any node , cannot take advantage of the high performance of the node. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a method and an apparatus for executing computing tasks, which can simultaneously ensure the high per...
