             Summary: Improve spacing on distinct versions message
                 Key: HADOOP-14575
                 URL: https://issues.apache.org/jira/browse/HADOOP-14575
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Alan Jackoway
            Priority: Minor


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.
