[jira] [Commented] (YARN-9495) Fix findbugs warnings in hadoop-yarn-server-resourcemanager module

    [ https://issues.apache.org/jira/browse/YARN-9495?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16820158#comment-16820158 ] 

Adam Antal commented on YARN-9495:
----------------------------------

Thanks for noticing that. 
It looks appropriate to add these to findbugs-exclude. Just for sure, could you trigger jenkins on your patch (setting this issue Patch available)?

> 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 com.google.common.util.concurrent.SettableFuture#set even through they are indeed declared as Nullable, 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.
