--------------------------------------
Summary: FS Preemption is a trickle for severely starved
applications
Key: YARN-6163
URL: https://issues.apache.org/jira/browse/YARN-6163
Project: Hadoop YARN
Issue Type: Sub-task
Components: fairscheduler
Affects Versions: 2.9.0
Reporter: Karthik Kambatla
Assignee: Karthik Kambatla
With current logic, only one RR is considered per each instance of marking an
application starved. This marking happens only on the update call that runs
every 500ms. Due to this, an application that is severely starved takes
forever to reach fairshare based on preemptions.
