--------------------------------------------
Summary: Scheduling of long-running applications
Key: YARN-5468
URL: https://issues.apache.org/jira/browse/YARN-5468
Project: Hadoop YARN
Issue Type: New Feature
Components: capacityscheduler, fairscheduler
Reporter: Konstantinos Karanasos
Assignee: Konstantinos Karanasos
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.
