----------------------------------
Ye, I will change it.
> Bad exception if multiple jars exist when running PySpark

> Found multiple Spark assembly jars in

> It's trying to read the Java gateway port as an int from the sub-process'
> STDOUT. However, what it read was an error message, which is clearly not an
> int. We should differentiate between these cases and just propagate the
> original message if it's not an int. Right now, this exception is not very
> helpful.
