> Reported source for config property can be misleading

>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: conf
>    Affects Versions: 0.23.3
>            Reporter: Jason Lowe

> Configuration.set tries to track the source of a property being set, but it mistakenly
reports properties as being deprecated when they are not.  This is misleading and confusing
for users examining a job's configuration.
> For example, run a sleep job and check the job configuration on the job UI.  The source
for the "mapreduce.job.maps" property will be reported as "job.xml ⬅ because mapreduce.job.maps
is deprecated".  This leads users to think mapreduce.job.maps is now a deprecated property
and wonder what other property they should use instead.
