> Hello,
> We are using Databricks on Azure to process large amount of ecommerce data.
> Databricks runtime is 7.3 which includes Apache spark 3.0.1 and Scala 2.12.
> During processing, there is a groupby operation on the DataFrame that
> consistently gets an exception of this type:
>
> {color:#ff0000}PythonException: An exception was thrown from a UDF: 'OSError:

> Code that causes this:
> {color:#ff0000}x = df.groupby('providerid').apply(domain_features){color}
> {color:#ff0000}display(x.info()){color}
> Dataframe size - 22 million rows, 31 columns
> One of the columns is a string ('providerid') on which we do a groupby
> followed by an apply operation. There are 3 distinct provider ids in this
> set. While trying to enumerate/count the results, we get this exception.
> We've put all possible checks in the code for null values, or corrupt data
> and we are not able to track this to application level code. I hope we can
> get some help troubleshooting this as this is a blocker for rolling out at
> scale.
> The cluster has 8 nodes + driver, all 28GB RAM. I can provide any other
> settings that could be useful.
> Hope to get some insights into the problem.
> Thanks,
