             Summary: Add error messages when Python worker could not open socket in `_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


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.
