Subject [jira] [Created] (YARN-1913) Cluster logjam when all resources are consumed by AM
Date Tue, 08 Apr 2014 16:20:20 GMT
bc Wong created YARN-1913:
-----------------------------

             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.
