Jason Lowe created HADOOP-8967:
----------------------------------
Summary: Reported source for config property can be misleading
Key: HADOOP-8967
URL: https://issues.apache.org/jira/browse/HADOOP-8967
Project: Hadoop Common
Issue Type: Bug
Components: conf
Affects Versions: 0.23.3
Reporter: Jason Lowe
Priority: Minor
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.
