      Description

      Chukwa has a flexibility to view the time series metrics graphs in different time range (5 min, hourly, daily, etc).
      The time unit of X axis is averaged to 5 minutes, 30 minutes, and 3 hours base on the time range selected. Some
      metrics may not have normalized time unit, and the graph representation does not the expected value.

        • Added exception handling for calculating stats for null data.
        • Improve rate calculation for accumulated values.
        • Remove time normalization for hadoop widgets because time normalization is done in demux now.
