Jonathan Eagles created YARN-4376:
-------------------------------------

             Summary: Memory Timeline Store return incorrect results on fromId paging
                 Key: YARN-4376
                 URL: https://issues.apache.org/jira/browse/YARN-4376
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jonathan Eagles
            Assignee: Jonathan Eagles


As pointed out correctly by [~jlowe]. 

https://issues.apache.org/jira/browse/TEZ-2628?focusedCommentId=14715831&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14715831

The MemoryTimelineStore cannot page correctly when using fromId. This is due switching between
data structures that apparently have different natural sorting. In addition, the approach
of creating a new data structure every time from scratch is costly.
