> Key: HADOOP-8967

> 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.
