PipelineParameter default values in DatabricksStep

[jarandaf]

It seems only string types are supported. int/float types throw the following error:

.../lib/python3.7/site-packages/azureml/pipeline/core/_databricks_step_base.py", line 569, in _encode_string_params
    final_params_list.append(value.replace("|", "|-"))
AttributeError: 'int' object has no attribute 'replace'

I don't see this behavior when using pipeline parameters in PythonScriptStep.

The error says that you cannot do a replace on an int object - which means that the param you are adding is an int.
Can you please provide some more details of what you are trying to do here?

[jarandaf]

From what I can see, DatabricksStep arguments validation is different than the one performed by a PythonScriptStep. The former does not support any other type than str for a PipelineParameter default value while the latter does. Can anyone please confirm? Is this the expected behavior?

that is not expected behavior and should be considered a bug

(it looks as simple as casting value to str in the initial code snippet)

[jarandaf]

Yeah, that's what I do as a workaround. Moreover I think that other basic types as list should also be supported (right now they aren't).

@jarandaf Thank you for bringing this to our attention. I have opened a work item to address this change. Once approved by our engineering team, it will be taken up in our planning and release cycle.
