------------------------------
Summary: Proposal of Guaranteed Capacity Scheduling for YARN
Key: YARN-3807
URL: https://issues.apache.org/jira/browse/YARN-3807
Project: Hadoop YARN
Issue Type: Improvement
Components: capacityscheduler, fairscheduler
Reporter: Wei Shao
This proposal talks about limitations of the YARN scheduling policies for SLA
applications, and tries to solve them by [Link] and the new scheduling policy
called guaranteed capacity scheduling.
Guaranteed capacity scheduling makes guarantee to the applications that they
can get resources under specified capacity cap in totally predictable manner.
The application can meet SLA more easily since it is self-contained in the
shared cluster - external uncertainties are eliminated.
