Description

When I view the job details page of a job running on a standalone cluster, I see the following strange output:

Cores: 2147483647 (400 Granted )

I'm not sure where 2147483647 is coming from (it's Integer.MAX_VALUE).

Looking at the code for this job details page, this is generated by the following:

        <li><strong>Cores:</strong>                                             
          @job.desc.cores                                                       
          (@job.coresGranted Granted                                            
          @if(job.desc.cores == Integer.MAX_VALUE) {                            
                                                                                
          } else {                                                              
            , @job.coresLeft                                                    
          }                                                                     
          )                                                                     
        </li>     

I'm not sure what this is supposed to do; is the idea to display something like "Cores: totalCores (x granted, y pending)"? Does Integer.MAX_VALUE have any special significance when used as the number of cores in a JobDescription?
