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

[~chris.douglas] This would be a good change to merge to branch-2 and 
branch-2.1.0-beta.
                
> Add Configuration API for parsing time durations

> Hadoop has a lot of configurations which specify durations or intervals of 
> time. Unfortunately these different configurations have little consistency in 
> units - eg some are in milliseconds, some in seconds, and some in minutes. 
> This makes it difficult for users to configure, since they have to always 
> refer back to docs to remember the unit for each property.
> The proposed solution is to add an API like {{Configuration.getTimeDuration}} 
> which allows the user to specify the units with a postfix. For example, 
> "10ms", "10s", "10m", "10h", or even "10d". For backwards-compatibility, if 
> the user does not specify a unit, the API can specify the default unit, and 
> warn the user that they should specify an explicit unit instead.
