--------------------------------------
Summary: Experiment with using PriorityQueue for storing starved
applications
Key: YARN-5893
URL: https://issues.apache.org/jira/browse/YARN-5893
Project: Hadoop YARN
Issue Type: Sub-task
Components: fairscheduler
Affects Versions: 2.9.0
Reporter: Karthik Kambatla
FSStarvedApps currently uses a BlockingQueue to store starved applications.
This leads to storing the apps in the order they were processed instead of
their priorities. Using a PriorityQueue will ensure we preempt for the highest
priority apps first.
