Sunil G commented on YARN-6600:
-------------------------------

Thanks [~rohithsharma]

Some more minor nits:
# In {{UpdateApplicationTimeoutsResponsePBImpl #setApplicationTimeouts}}, IIUC *applicationTimeouts*  needs to be cleared when *appTimeouts* is null.
# {{@param lifetime requestedByApp}} could be {{lifetime configured application lifetime}}
# Since below variables are in LeafQueue, could we add Application also in variable name.
{code}
private volatile long maxLifetime = -1;
private volatile long defaultLifetime = -1;
{code}
like maxApplicationLifetime and defaultApplicationLifetime
# It ll be fine to add one test case for other schedulers to ensure the feature is not switched on.

> Setting timeout at LeafQueue level allows admin to control from bad apps which uses most of the resources for all the time. 
> Example : Any application submitted to particular queue i.e QUEUE-1 should not  run more than N hours. Even user set lifetime as N+1 hour, the application will be killed after N hours.
