I run the startup.bat in target folder and keep getting this Exception.I’ve tried so many times but still couldn’t solve it.

Anyone here please help me out?

I know this is old, but just saw it. Ignore those exceptions, they come from a try/catch block that catches Exception – acting like a catch-all to prevent a LaF from crashing Spark. I’ve always had those eceptions at startup as well…
