问题 I have been using Spark + Python to finish some works, it's great, but I have a question in my mind: where is the spark job of transformation and action done? Is transformation job done in Spark Master ( or Driver ) while action job is done in Workers ( Executors ), or both of them are done in Workers ( Executors ) Thanks 回答1: Workers (aka slaves) are running Spark instances where executors live to execute tasks. Transformations are performed at the worker, when the action method is called

Why Wordpress action callback does not fire when added inside function

三世轮回 提交于 2020-06-29 04:28:26
问题 I'm wondering why add_action( 'admin_post_nopriv_myAction', 'myCallback' ); does not fire when I add it inside a function, but it does work when added outside a function. See examples below. I minimized the code a bit to show the idea. In reality a form is output in the shortcode function and processed in the callback. This one does not fire the callback: function my_shortcode() { add_action( 'admin_post_nopriv_myAction', 'myCallback' ); add_action( 'admin_post_myAction', 'myCallback' );
