Spark will not start

After I installed spark 2.3.6 and reboot, I click on the icon to start it up and all I get is an hour glass for a split second then nothing ever happens. I have tried to uninstall (which it does successfully) then reinstall it and the same thing happens. I have tried re downloading it and installing agian … still same thing. Quick hour glass and then nothing. Any ideas?

Sorry the version is 2.5.6 not 2.3.6

Hi,

do you see errors in the log files?

On Windows they are located in “%programfiles%\spark\logs” and in “%userprofile%\spark\logs”.

This is what is in the error logs.

I am reinstalling Java now

Hi,

while I wonder if this is the start of the exception … did you run a Spark 2.x version before? Maybe one of the configuration files in “%userprofile%\spark” is corrupt. Renaming / Deleting the “%userprofile%\spark” folder would help in this case.

I did have it running last week. I will try deleting the profile and see if that helps. Oh and reinstalling the Java did nothing.

Thanks

I will let you know

That did it THANK YOU
