[jira] [Created] (KYLIN-3569) Server with query mode still can submit/build job

Zongwei Li created KYLIN-3569:
---------------------------------

             Summary: Server with query mode still can submit/build job
                 Key: KYLIN-3569
                 URL: https://issues.apache.org/jira/browse/KYLIN-3569
             Project: Kylin
          Issue Type: Bug
          Components: Job Engine, REST Service, Security
    Affects Versions: v2.4.1
         Environment: CentOS 6.7, HBase 1.2.0+cdh5.14.2+456
            Reporter: Zongwei Li


From the Docs at Kylin site, [http://kylin.apache.org/docs24/install/kylin_cluster.html]
 * *query* : run query engine only; Kylin query engine accepts and answers your SQL queries

It seems that if server set with 'kylin.server.mode=query', it should not can support submit/build job. But as we tested, server with query mode still can submit/build job from UI or RESTFul API. 

We analyzed the source code, found that there didn't exist any protect logic to check whether server is at 'job' or 'build' mode in service layer for submit/build job. Will attach the source code is this issue.

This issue really confused us, because we considered query server cannot build job in Kylin Docs and many Kylin books. And query server will exposed to 3rd BI tool to query the data, if we forget to configure the suitable ACL for Cubes, then the 3rd BI tool can trigger build job in any time.
