Description

when client excute shell "mapred job -list",

                                 JobId	         State	           StartTime	           UserName	       Queue	  Priority	 UsedContainers	 RsvdContainers	
 job_1467197069300_0002	   RUNNING	 1470405744358	               hdfs	                    default      DEFAULT	              1	              0	 

the result shows StartTime is a long type，which is not user-friendly.
and command "mapred queue -info -showJobs" has common problem.
