Bikas Saha commented on YARN-2261:
----------------------------------
Sounds reasonable. Though things like how does YARN expose this information to
the user would eventually need to be thought about. Currently the RM page shows
running applications. How will show cleanup in progress? Can the original AM be
preempted due to lack of resources? In that case, how will we launch the clean
up container. Though probably the same problem exists now because if an AM is
preempted it would not be able to clean up. However, moving this responsibility
from the user to YARN (as proposed in this jira) makes that a YARN problem to
solve.
