Spark StartUp

now I am doing the secondary development on Spark, but I found that when I package into an EXE file, the Spark only support one instance that is when I have the Spark Client on, I cann’t start the Spark by another account, when I check the code, there is not any sign of the code that have this kind of constraints…

so there is the question that is the install4j work or the code of the spark work for this kind of constraints?

thanks for answer…
