Hitesh Shah commented on YARN-791:
----------------------------------
[~sandyr] I put in a similar comment on YARN-727. In my opinion, we could make
a cleaner api where passing null as the state filter returns all nodes ( both
in the RPC as well as the REST webservices ). Adding a state acts as a filter.
For usage in the CLI tools that returned only healthy nodes, the tools could be
changed to pass in the correct state filter to the api.
If there are other components that rely on this, we could change them to start
passing in the correct state to filter for healthy nodes only.
Obviously this is a behavior change which may be cause problems for a lot of
reasons. Given that the CLI tools and MapReduce are probably the only 2 major
users of this api, it might be better to bite the bullet and make the changes
now?
