Nitiraj Singh Rathore commented on AMBARI-19062:
------------------------------------------------

In Hive 1.5.0, the execution of the job has been moved to background threads 
and hence if the user goes away(closes) from the browser, the job still 
continues to run in the backend and will finish with a valid terminal 
state(either FAILED or SUCCESS). Previously this was not the case because all 
query to HS2 used to stop when the user closed the browser and hence to get the 
final terminal state we had to query ATS so that we could update the results in 
Hive browser database. The update used to happen when the user clicked on the 
history tab. So, for every job we used to query ATS for getting the terminal 
state. In the process it also used to bring in the information for the queries 
that were not run from the hive browser(may be from beeline or hive cli).
So, to fix this issue we are going to stop the call for ATS when the user 
clicks on the history tab. Because as execution has moved to background 
threads, the state of the job in the database is going to be always correct and 
we will consider that to be the source of truth.
The thing that we will miss out are the display of the jobs that are not run 
from hive browser, but to meet the SLA for the history tab and till the time 
ATS does not provide a bulk API to fetch the information we will have to miss 
that feature.
