Jinjiang Ling updated YARN-6837:
--------------------------------
    Attachment: YARN-6837-1.patch

[~jlowe] Thanks for your suggestion.
It seems that -[YARN-6403|https://issues.apache.org/jira/browse/YARN-6403]-  is similar to this error. I also find that the resource type is null will cause this error, so I add resource visibility and type check after it.

Update patch.
