Doug Cutting commented on HADOOP-3407:
--------------------------------------
This would be expensive as long as configurations are implemented with a hash
table.
Also, what are some use cases?
> Provide a query method to find all of the attributes under a given root

> It would be really nice to have a way to query all of the attributes under a
> given root:
> {code}
> String[] attrs = conf.getChildAttributes("mapred.task");
> {code}
> which would return all of the attributes in the configurat that start with
> "mapred.task...."
