Varun Vasudev commented on YARN-3678:
-------------------------------------
[~zhiguohong] thanks for the detailed explanation! When you say your fix
reduced the rate to nearly zero, do you know why the accidental kill continued
to happen?
> DelayedProcessKiller may kill other process other than container
