-------------------------------
Resolution: Won't Fix
> 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: Job Engine
> Reporter: Yerui Sun
> Assignee: Su Ralph
> Labels: newbie
>
> 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.
