Subject [jira] [Commented] (YARN-3454) RLESparseResourceAllocation does not handle removal of partial intervals
Date Tue, 07 Apr 2015 01:30:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-3454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482370#comment-14482370
] 

Carlo Curino commented on YARN-3454:
------------------------------------

Adding a capacity reservation (e.g., 10 containers) between time 10 and 20, and then removing
the same containers from an interval between 12-18 does not work correctly. Only exact interval
match work. This is normally not exercised in the Reservation sub-system, but for further
enhancements we are working on this is needed. More generally this is a bug we should get
rid off.

> The RLESparseResourceAllocation.removeInterval(...) method handles well exact match interval
removals, but does not handles correctly partial overlaps.
