Karthik Kambatla commented on YARN-1068:
----------------------------------------

Thanks [~bikassaha], agree with most of your points.

bq. AdminService does not use the HAServiceProtocolServerSideTranslatorPB 
pattern
The reason for this is our attempt to reuse most of the common code - protos 
and client implementations.

bq. Having thought about this, it seems to me that this jira is actually 
blocked by YARN-986.
To fix the admin support in entirety, I agree that we need YARN-1232 and 
YARN-986. That said, for ease of development, I would propose splitting the 
admin support into two parts (JIRAs) - basic support (this JIRA) to go in first 
to help testing YARN-1232 and YARN-986, and complete admin support that adds 
the remaining parts. Otherwise, we need applying this over those other JIRAs to 
test. Thoughts?
