             Summary: N/A Job Tracking URL in Build WebUI
                 Key: KYLIN-1339
                 URL: https://issues.apache.org/jira/browse/KYLIN-1339
             Project: Kylin
          Issue Type: Bug
          Components: Web 
            Reporter: Yerui Sun

By designing, the cuboid building steps on web ui has the url directed to the job page on yarn. 
In fact, the url can't be always retrieved successfully. The url is 'N/A' sometimes, or added a prefix 'unsafe:' sometimes, or the right link sometimes. With some debug log, founded that the url was fetched from status info, which filled by job.getTrackingURL() in HadoopCmdOutput.getInfo() when check job status in MapReduceExecutable. The job tracking url was 'N/A' at the first 20 seconds since job started, and became the right link after that. One possible reason is that the tracking url is valid until AppMaster started, which started slowly.
There's still one question, the job status checking was executed periodically, and the status info should filled with job tracking url after some seconds later, but the web ui link was not updated.
Some more digging is needed for this issue.
