Botong Huang commented on YARN-9049:
------------------------------------

Understood. Let me ask this way: forget about implementation details, in 
general, why would adding future app data entry in _ApplicationData_ be easier 
than adding it directly in _ApplicationHomeSubCluster_?

I think at API/interface level, the latter makes more sense because 
_ApplicationHomeSubCluster_ should already serve as _ApplicationData_ if not 
renamed to it. If for mysql implementation, the former is easier (by adding a 
extra layer), then this should be kept implementation specific, and not exposed 
to the API?
