Hi everyone. I'm training a time series forecasting model in Azure Databricks. When I try to parallelize, it gives me this error:

Can't you use data frames API? Using RDD directly is an outdated method as it is not optimized. Dataframe is automatically distributed (parallelized using partitions and cores). Additionally, how big is a dataset? as running collect() is also a killer and should not be used in production or to return more than a dozen rows.
