[jira] [Commented] (YARN-7539) NullPointerException in timeline
service v2
[ https://issues.apache.org/jira/browse/YARN-7539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16259762#comment-16259762 ]
Vrushali C commented on YARN-7539:
----------------------------------
Hmm. Interesting.. And you saw this was thrown after the job has finished? Do you know what happens after this... Is the history file generated? Does the application show failed status or something else?
Also, is the NPE printed once or many times? Basically wondering if the timeline collector is retrying or something and keeps throwing this error.
