In similar lines, it would > be nice if the FairShare Scheduler can have a pluggable policy to regulate > new tasks from a particular job. This will allow one to skip scheduling tasks > of a job that is eating a large percentage of memory in the cluster, i.e. > fair-share of memory resources among jobs. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
