Zhijie Shen commented on YARN-2656:
-----------------------------------

bq. I think we should use "hadoop.proxyusers" instead of introducing 
"yarn.resourcemanager.proxyusers".

KMS and HTTPFS are using this feature as well, but using their individual 
prefix before "proxyusers". I think it makes sense because each component can 
edit its own proxyusers. In particular, it's desired in single-node cluster. 
Thinking about the property name again, should we use 
"yarn.resourcemanager.webapp" to be consistent with the existing YARN config 
names?

> RM web services authentication filter should add support for proxy user

> The DelegationTokenAuthenticationFilter adds support for doAs functionality. 
> The RMAuthenticationFilter should expose this as well.
