    [ https://issues.apache.org/jira/browse/YARN-8549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16638524#comment-16638524 ]

As [~suma.shivaprasad] suggested, I replaced the NULL with an empty TimelineWriterResponse object. I will also address your concerns on adding a debug log when the stubs are being used on a node.
