>            Reporter: Alan Jackoway

>
> I was upgrading my cluster today and saw that the mixed versions message on 
> the namenode UI was like this:
> {{There are 2 versions of datanodes currently live:v1 (20) ,v2 (10)}}
> This commit should put a space after the : and change it so the comma is 
> before its space, like this:
> {{There are 2 versions of datanodes currently live: v1 (20), v2 (10)}}
> I have not tested this change. I'm not familiar with the templating language 
> unfortunately, so I made my best guess.
