    Description

      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
