Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0043] Spark is a general-purpose big data computing engine, often used for real-time computing or offline computing. For Spark real-time computing tasks, once released, continuous computing is required 7*24 hours a day. During the running of the Spark task, the configuration information of the current task cannot be modified in real time. In order to change the configuration information during the running of the Spark task, the following technical solutions ar...

Abstract

The invention relates to a method, a device and a system for dynamically changing Spark user configuration. The method comprises the following steps: receiving latest configuration information sent bya user by utilizing a preset resful interface; broadcasting the latest configuration information by using a preset broadcast variable in the Spark, wherein all Executor actuators in an execution taskacquire the latest configuration information to change the configuration information. By adopting the method, the device or the system, the user configuration information in the task can be dynamically changed in the task running process, and the flexibility of the Spark task is improved.

Description

technical field [0001] The invention relates to the technical field of Spark task configuration, in particular to a method, device and system for dynamically changing Spark user configuration. Background technique [0002] At present, many businesses in the Internet field involve the processing of big data, such as advertisements, reports, and recommendation systems. In the above businesses, big data needs to be used for corresponding data analysis and personalized recommendations. The amount of calculation involved in the processing of existing big data is extremely large. In this case, the Spark computing engine is used for big data processing. In Spark, two nodes, driver and executor, perform data processing. Among them, driver is the driver node of Spark, which is used to execute the main method in the Spark task and is responsible for the actual code execution. Executor is the executor node of Spark, which is responsible for running specific tasks in Spark jobs, and t...
