Íñigo Goiri commented on YARN-996:
----------------------------------
This is the same approach followed in {{ResourceOption}}.
The idea is that you only create the object if it's needed for extracting.
When this happens is cached and then returned the cache all the time.
{{getResourceOption()}} cannot go into NPE as it's just the previous check that
we do where we create the cached object.
The only one that would cause an NPE is the contructor with a null
ResourceOption.
