Varun Saxena commented on YARN-4490:
------------------------------------

bq. The Diagnostic message should be available only for the application waiting 
for allocation.
Not necessary. Diagnostics are not only meant to tell if app is waiting for 
allocation. YARN-3946 merely added to current diagnostics.

> RM restart the finished app shows wrong Diagnostics status
