Tao Jie updated MAPREDUCE-7040:
-------------------------------
    Description: Now in JobHistoryServer, jobs are ordered by JobID in a 
datatable. JobID here is interpreted as a string rather than parsing the id 
number from the JobID. As a result, jobID 
[job_1516090502319_|http://cmhtj1:19888/jobhistory/job/job_1516090502319_0001]9999
 is alway in front of  
[job_1516090502319_|http://cmhtj1:19888/jobhistory/job/job_1516090502319_0001]10123
 while the latter is the newer job.  (was: Now in JobHistoryServer, jobs are
