Vertex.setConf介绍

[英]This is currently used to setup additional configuration parameters which will be available in the Vertex specific configuration used in the AppMaster. This API would be used for properties which are used by the Tez framework while executing this vertex as part of a larger DAG. As an example, the number of attempts for a task.

A vertex inherits it's Configuration from the DAG, and can override properties for this Vertex only using this method

Currently, properties which are used by the task runtime, such as the task to AM heartbeat interval, cannot be changed using this method.

Note: This API does not add any configuration to runtime components such as InputInitializers, OutputCommitters, Inputs and Outputs.
[中]这目前用于设置附加配置参数，这些参数将在AppMaster中使用的特定于顶点的配置中可用。该API将用于Tez框架在作为更大DAG的一部分执行该顶点时使用的属性。例如，任务的尝试次数。
顶点从DAG继承其配置，并且只能使用此方法覆盖该顶点的属性
当前，无法使用此方法更改任务运行时使用的属性，例如任务到AM心跳间隔。
注意：此API不会向运行时组件（如InputInitializers、OutputCommitter、Inputs和Outputs）添加任何配置。
