             Summary: When NoClassDefFoundError occurred in building cube, no error in kylin.log
                 Key: KYLIN-2342
                 URL: https://issues.apache.org/jira/browse/KYLIN-2342
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v2.0.0
            Reporter: Shaofeng SHI
            Assignee: Shaofeng SHI
             Fix For: v2.0.0


When some jar is missing in kylin, trigger the cube build will get error, but there is no any warn/error message in backend kylin.log; The front web page also doesn't provide much message. Finally I get the root cause in the HTTP response.

The error should not be exposed to web gui; at least some trace need be left in kylin.log:

Below is the error in HTTP response:
