Subject [jira] [Created] (UIMA-4275) DUCC RM: Rework constraints on class usage
Date Thu, 05 Mar 2015 16:04:39 GMT
Jim Challenger created UIMA-4275:

             Summary: DUCC RM: Rework constraints on class usage
                 Key: UIMA-4275
                 URL: https://issues.apache.org/jira/browse/UIMA-4275
             Project: UIMA
          Issue Type: Improvement
    Affects Versions: 1.1.0-Ducc
            Reporter: Jim Challenger
            Assignee: Jim Challenger
             Fix For: 2.0.0-Ducc

The current class constraints are per-allocation and not sufficiently constraining in that
a user can dominate a cluster with many requests for non-preemptable shares.

There are proposals for user-based limits (max allocations per user), group-based limits (group
membership determines limits), and project-based limits (submission to authorized projects
determines limits).

The final decision is still open.  This JIRA will track progress and eventually, the implementation.
