Unable to start selenium grid properly within java code to perform parallel test

[akamel...@gmail.com]

Im trying to start selenium grid programmatically but i have and issue dont know exactly how to solve it.

im running appium test using page object model and appium server start programmatically in two sessions for two android devices and its working properly when i open selenium grid from terminal using the common code "java -jar selenium-server-standalone-3.141.59.jar -role hub

" 

but now i want to start also selenium grid within my script so once its initiated appium server it will detect the localhost and register the node config files ,perform the test and after test is finished appium server will stop then selenium grid session will be terminated as well.

also im wondering why i have to set config for selenium grid? can i start it in default configuration like if "java -jar selenium-server-standalone-3.141.59.jar -role hub

" since already node config are loaded with the appium server.
