Spark 2_5_6 will not open

Hello All,

I installed Spark 2_ 5_6 on my computer and it worked fine on the first day. Now, Whenever I open Spark, nothing happens. In Task mgr, you see the icon appear for about 10-20 Sec and it disappears after. I uninstalled it and re-installed it but no luck. Anyone know what the porblem might be?

HI Dana

Can you start by checking your error.log and spark-error.log under the logs directory of your spark installation directory. THe entries in here should give people a bit more info to help diagnose the problem.

Sorry for the delay. I tried to login and give you the log but the site was down. Anyway, in the meantime, I went searching for the solution based on the error message in error.log. The error was “Caused by: java.lang.NullPointerException”. Found a site that pointed to my settings.xml file being corrupted. So, I deleted the spark folder from my documents and settings. This solved the problem and I am now able to login. Just for kicks, below is the error.log. And the site that I found the solution at is: http://eval.jivesoftware.com/forums/thread.jspa?threadID=21128&tstart=425. I appreciate your help in pointing me to the log file.
