> in JDBCRDD, it has
> if (!conn.getAutoCommit && !conn.isClosed) {
>             try {
>               conn.commit()
>             } 
> . . . . . .
> In my test, the connection is already closed so conn.getAutoCommit throw Exception. We should check !conn.isClosed before checking !conn.getAutoCommit to avoid the Exception.
