Vrushali C created YARN-4069:
--------------------------------
Summary: For long running apps (> 2 days), populate flow activity
table
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.
