How to read Pipeline parameters configured in DataFactory from notebook

[tsrikanth06]

You created a parameter with name 'name', but inside the notebook you are reading as 'input'. How does it map 'input' to 'name', aslo getArgument() takes two arguments
error: not enough arguments for method getArgument: (argName: String, defaultValue: String)String.

Even after providing default value, getArgument did not read the parameter I passed via DataFactory.
Can you please give a code snippet on how to read pipeline parameters from notebook.
Aslo while configuring notebook in dataFactory, there is 'User Properties', whats the difference between 'User Properties' and Pipeline 'Parameters'. How to read 'User Parameters' from notebook.

@tsrikanth06 Thanks for your feedback! We will investigate and update soon on it.

@tsrikanth06 I just tried the tutorial and it worked fine for me.

'input' gets mapped to 'name' because 'input' = @pipeline().parameters.name.

When the pipeline is triggered, you pass a pipeline parameter called 'name':

Here is more information on pipeline parameters:

yeah it works, Thanks
I built a pipeline and notebook on Failure triggers web activity. But when notebook fails, like with exception, DataFactory fails with errorCode:3204 and failureType: UserError and it does not trigger web activity.
How can I treat UserError as Failed or is there a way my notebook can throw exception and dataFactory can catch the exception and treat it as Failure

The issue reappears - today I also had the same problem. Looks like "input" is reserved word, when you rename it to "input_path" is starts working. Here is open issue on this - #42281. Please fix it in tutorial otherwise tutorial just doens't work - https://docs.microsoft.com/en-us/azure/data-factory/transform-data-using-databricks-notebook
