-----------------------------------
Summary: Scheduler restart does not preserve app start time
Key: YUNIKORN-2772
URL: https://issues.apache.org/jira/browse/YUNIKORN-2772
Project: Apache YuniKorn
Issue Type: Bug
Components: shim - kubernetes
Reporter: Mit Desai
Assignee: Wilfred Spiegelenburg
Whenever the scheduler is restarted, all the applications create time is set to
the current time, ignoring the original value that comes from the API server.
Due to this, FIFO sorting can show irregularity in scheduling.
If there is an App1 that started 2 days ago and App2 that started 1 day ago,
during scheduler restart, both the apps will get almost same created time (nano
seconds apart). App2 create time can be just a few nano seconds ahead of App1
and hence App2 gets priority over App1
