Subject [jira] [Commented] (YARN-4061) [Fault tolerance] Fault tolerant writer for timeline v2
Date Tue, 28 Feb 2017 22:29:45 GMT

    [ https://issues.apache.org/jira/browse/YARN-4061?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15888979#comment-15888979
] 

Sangjin Lee commented on YARN-4061:
-----------------------------------

[~haibochen], is your comment a general comment on what that method is doing, independent
of this JIRA? If so, I think that is correct. It must be a bug. Today there is no caller for
that flavor of the {{store()}} method, but we should still fix it. Do you mind opening a new
JIRA to fix that? Have you checked other {{store()}} methods to see if there is any other
similar issue?
