Vrushali C created YARN-4069:

             Summary: For long running apps (> 2 days), populate flow activity 
                 Key: YARN-4069
                 URL: https://issues.apache.org/jira/browse/YARN-4069
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Vrushali C

YARN-4063 / YARN-3901 contain the work being done to populate the flow activity 
and flow run tables.

The flow activity table is updated each time a yarn application is created and 
finishes. So if an application runs for more than 3 days, day1 has an entry for 
the flow for start time, day3 has an entry for the flow for end time but day2 
has no entry for that flow. 

Filing the jira to ensure that for long running apps, the flow activity table 
does get a snapshot time entered for each day that an application is running in 
that flow.

It may be the case that for ALL apps (long running or not) the same update may 
be done in the flow activity table.
