Subject [jira] [Commented] (YARN-4061) [Fault tolerance] Fault tolerant writer for timeline v2
Date Tue, 28 Feb 2017 22:46:45 GMT

    [ https://issues.apache.org/jira/browse/YARN-4061?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15889016#comment-15889016
] 

Haibo Chen commented on YARN-4061:
----------------------------------

I found this during my attempt to do coprocessor refactoring and did not see any other similar
cases. I recall it was mentioned in one of our fault-tolerant writer discussion that ATS clients
set the timestamp explicitly, but I was not sure if this is a real bug or not. That's why
I posted it here. Filed YARN-6253.
