Answered 2021-Jan-28 at 11:00For your question regarding the events. Below are the links explaining what those two events do.
- For the tabStrip events : https://docs.telerik.com/kendo-ui/api/javascript/ui/tabstrip/events/show
- For the grid events : https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/events/databound
Here in your code, you don't need to do anything in your dataBound event.
For the rest :
You should start by writing your controler action the same way it is described on the documentation : https://demos.telerik.com/aspnet-mvc/grid/remote-data-binding

Answered 2020-Mar-06 at 11:07There seem to be a few issues with your code and your POM.
Talking about the code, you have created a sparksession and a sparkcontext separately even though you can just create the SparkSession object and it has the sparkcontext present. Also, you have set the spark properties in both your code and your spark-submit command. I recommend you create a separate sparkProperties file and pass it onto your spark-submit command (I'll share the file and the command too).
