Tao Yang updated YARN-9495:
---------------------------
Description:
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.
