Eric Yang commented on YARN-8525:
---------------------------------
After discussing with [~billie.rinaldi], the catching of interrupts will
prevent yarn --daemon stop to do forceful kill instead of SIGTERM shutdown
because the patch will capture the interrupt and continue to run. The new
behavior is more forceful, and doesn't seem desired in day to day function of
the daemon service. Hence, we decided to not fix this bug.
