Review comment:
Do you mean that we should search for an entry class both in the user
classpath and system classpath?
I have a little concern about that. If there is only an entry class in the
system class and we use it. I think it leads to the jars in the job directory
will not be used. It is a little weird that the user provides some jars but
could not be used.
