[jira] [Created] (AURORA-733) MedianAlgorithm results should be windowed in time

Bill Farner created AURORA-733:
----------------------------------

             Summary: MedianAlgorithm results should be windowed in time
                 Key: AURORA-733
                 URL: https://issues.apache.org/jira/browse/AURORA-733
             Project: Aurora
          Issue Type: Story
          Components: Scheduler, SLA
            Reporter: Bill Farner


{{MedianAlgorithm}} computes the median of numeric values extracted from {{IScheduledTask}}s.  Unlike other {{SlaAlgorithm}} implementations, it ignores the {{timeFrame}} argument, and computes the median for all tasks provided.  This results in a graph that is historically-weighted, and less responsive to load.  Consider using the {{timeFrame}} to filter tasks before computing the mdeian.
