Summary: FairScheduler.maxTasksToAssign() should check for fairscheduler.assignmultiple.maps < TaskTracker.availableSlots Key: MAPREDUCE-4385 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4385 Project: Hadoop Map/Reduce Issue Type: Improvement Affects Versions: 1.0.3 Reporter: Karthik Kambatla Assignee: Karthik Kambatla FairScheduler.maxTasksToAssign() can potentially return a value greater than the available slots. Currently, we rely on canAssignMaps()/canAssignReduces() to reject such requests. These additional calls can be avoided by check against the available slots in maxTasksToAssign(). -- This message is automatically generated by JIRA.
