[jira] [Commented] (MAPREDUCE-4355) Add startTime to RunningJob

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13401616#comment-13401616 ] 

Karthik Kambatla commented on MAPREDUCE-4355:
---------------------------------------------

Arun, it might be cleaner to add RunningJob.getJobStatus() instead of adding startTime, endTime fields to RunningJob and redundantly maintaining them.

Thanks.

> To read the start-time of a particular job, one should not need to getAllJobs() and iterate through them.
> getJob(JobID) returns RunningJob, which doesn't hold the job's start time.
> Hence, we need to either add getJobStatus(JobID) to the API or add startTime to RunningJob. Doing the latter.
