Jiaqi Tan commented on CHUKWA-429:
----------------------------------
It looks like there are only a fixed number of colours available, and the
colours don't smoothly move with the values--is that true? Would it be
difficult to have rainbow colours with smoothly scaled colours?
> Refine the HDFS heatmap color map to look like rainbow color map
