JobHistory UI is not showing the running jobs.

I have a job running in the cluster, but I am unable to see that job through the JobHistory UI. I can only see the job if I execute the command "hadoop job -list" in the linux command prompt. I have observed that if I go to "ResourceManager UI" I see a running application, but I do not see any jobs of that running application through "JobHistory UI". In the ResourceManager UI, I have also observed that the latest application that I executed is associated with "ApplicationMaster' under "Tracking UI" field. Rest of the other Applications are associated with "History" under "Tracking UI" field. Is this the reason why I cannot see all the jobs under JobHistory UI for this application because it is associated with ApplicationMaster?.
