> 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.
