Subject [jira] [Commented] (YARN-5468) Scheduling of long-running applications
Date Tue, 02 Aug 2016 23:21:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15405002#comment-15405002

Konstantinos Karanasos commented on YARN-5468:
----------------------------------------------

We will shortly upload a first prototype just to get some initial feedback. In this first
patch we are introducing the placement constraints and extend the CapacityScheduler to take
them into account during scheduling.
We will soon upload a design document too.

> This JIRA is about the scheduling of applications with long-running tasks.
> It will include adding support to the YARN for a richer set of scheduling constraints
(such as affinity, anti-affinity, cardinality and time constraints), and extending the schedulers
to take them into account during placement of containers to nodes.
> We plan to have both an online version that will accommodate such requests as they arrive,
as well as a Long-running Application Planner that will make more global decisions by considering
multiple applications at once.
