Vinod Kumar Vavilapalli commented on YARN-1696:
-----------------------------------------------
I think the long term goal is to unify them but we aren't there yet. There are
users who want to enable RM restart only without failover today. Given that, I
think we should keep them separate till we have a complete story. When things
come together long term, we can link these together by using a top level doc.
Even then, I think after we go through the remaining phases in RM restart, the
doc at YARN-1017 will grow more and it's better to do what HDFS did - split
into well-defined pages.
This doc should instead be renamed "ResourceManager fail-over" and only focus
on that for now.
