             Summary: Add precision option support to Ambari Metrics API
                 Key: AMBARI-8973
                 URL: https://issues.apache.org/jira/browse/AMBARI-8973
             Project: Ambari
          Issue Type: Task
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
             Fix For: 2.0.0


Modify AMS API layer to switch precision level based on query window.
E.g.: Any query > 1 hour should get data from the 5 minute aggregate table 
unless user provides a precision parameter.
-startTime - endTime = 1 day OR precision = minutes
implies query => 5 minute table
-startTime - endTime = 3 hours and precision = seconds
implies query => minute table (METRIC_RECORD)
So, effectively we are just using the precision as guidance paramete
