Subject [jira] [Commented] (YARN-1051) YARN Admission Control/Planner: enhancing the resource allocation model with time.
Date Thu, 17 Dec 2015 20:05:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-1051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15062692#comment-15062692
] 

Carlo Curino commented on YARN-1051:
------------------------------------

[~lars_francke], you can refer to the general tech-report for more of the top-level ideas/design.
As for how-to-use documentation, you are right it is long overdue. A couple of follow up umbrella
JIRAs YARN-2573 (HA for the reservation system), and YARN-2572 (various improvements/extensions
and REST API work) can give you some more context of what is brewing. But, in particular,
as part of the umbrella JIRA YARN-2572, I have just opened YARN-4468 that is intended to provide
general documentation of the reservaiton system and its (recently added) REST api. We will
try to get to it soon.

> In this umbrella JIRA we propose to extend the YARN RM to handle time explicitly, allowing
users to "reserve" capacity over time. This is an important step towards SLAs, long-running
services, workflows, and helps for gang scheduling.
