> `_load_from_socket`.
> -----------------------------------------------------------------------------------
>
> Key: SPARK-25142
> URL: https://issues.apache.org/jira/browse/SPARK-25142
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 2.3.1
> Reporter: Takuya Ueshin
> Priority: Major
>
> Sometimes Python worker can't open socket in {{_load_from_socket}} for some
> reason, but it's difficult to figure out the reason because the exception
> doesn't even contain the messages from {{socket.error}}s.
> We should at least add the error messages when raising the exception.
