Which version of Kylin are you running? The web UI had a bug on showing the error messages, but it should have been fixed in v1.0; If you're using some browser side debug tool like firebug, you can check the content in the http response body; But usually we directly check the log file $KYLIN_HOME/tomcat/logs/kylin.log ; Please check it there, and you can copy/paste the detail error trace here for trouble shotting;
