--------------------------------------------------------------

Just to show how *inane* this is jira is, here are the colors measurements of 
Hortonwork's green, Cloudera Blue, and the original color using Mac's digital 
color meter:

|| Attribute || Hortonworks Green || HDFS Color || Cloudera Blue ||
| L | 69.52 | 33.94 | 34.4 |
| A | -44.68 | -22.34 | -17.68 |
| B | 60.91 | 26.88 | -19.98 |

so Hortonworks Green - HDFS Color = 35.58 + 22.34 + 34.03 = 91.95
and Cloudera Blue - HDFS Color = 0.46 + 4.66 + 46.86 = 51.98

Clearly we need to make the color greener to denote additional stability.

> The HDFS UI colors are too close to HWX green.
> Here is a patch that steers clear of vendor colors.
> I made it a blocker thinking this something we'd want to fix before we 
> release apache hadoop 2.3.0.
