Summary: Fix findbugs warnings in
hadoop-yarn-server-resourcemanager module
Key: YARN-9495
URL: https://issues.apache.org/jira/browse/YARN-9495
Project: Hadoop YARN
Issue Type: Bug
Reporter: Tao Yang
Assignee: Tao Yang

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.
