Lavkesh Lahngir updated YARN-4750:
----------------------------------
Description:
App metrics(rather app attempt metrics) like Vcore-seconds and MB-seconds are
saved in the state store when there is an attempt state transition. Values for
running attempts will be in memory and will not be saved when there is an RM
restart/failover. For recovered app metrics value will be reset. In that case,
these values will be incomplete.
Was this intentional or have we not found a correct way to fix it?
