> Recently there are 2 extant Findbugs warnings in hadoop-yarn-server-resourcemanager module according to the jenkins report of YARN-9439/YARN-9440 as follow:
>  !image-2019-04-17-18-22-40-624.png! 
> They seems not expect null input for SettableFuture#set even through they are declared as Nullable in com.google.common.util.concurrent.SettableFuture#set, perhaps since findbugs can support javax.annotation.Nullable but not org.checkerframework.checker.nullness.qual.Nullable. 
> I think we should exclude these two warnings through adding them into hadoop-yarn/dev-support/findbugs-exclude.xml.
