-----------------------------
Summary: Cluster logjam when all resources are consumed by AM
Key: YARN-1913
URL: https://issues.apache.org/jira/browse/YARN-1913
Project: Hadoop YARN
Issue Type: Bug
Components: scheduler
Affects Versions: 2.3.0
Reporter: bc Wong
It's possible to deadlock a cluster by submitting many applications at once,
and have all cluster resources taken up by AMs.
One solution is for the scheduler to limit resources taken up by AMs, as a
percentage of total cluster resources, via a "maxApplicationMasterShare" config.
