Eli Collins resolved HADOOP-3482.
---------------------------------

    Resolution: Won't Fix

Out of date

> Think to some modification to the API

>                 Key: HADOOP-3482
>                 URL: https://issues.apache.org/jira/browse/HADOOP-3482
>             Project: Hadoop Common
>          Issue Type: Improvement
>            Reporter: Brice Arnould
>            Priority: Minor
>
> I know that it is out of question to break everything just for minor comfort 
> improvements.
> But I think that we should evaluate the cost of improving the API, and the 
> way we might do this without too much breaks, before the API freeze of 1.0 . 
> If we start now, it could be a gradual process that would end only with the 
> 1.0 release.
> I do not particulary focus on those modifications, but here is a samples of 
> what questions I would like to raise.
> # Text could provide a append(Text other) method
> # Text could implements CharSequence
> # Some Iterators could be turned into IterableIterators.
> # We could consider a more consistent naming (Text could be renamed 
> TextWritable, JobConfigurable.configure() could be turn in 
> JobConfigurable.setConf() to match Configurable and so on)
> 1. and 2. seems imediatly accessible, even if 1. would benefit of the use of 
> a resizable container to store bytes.
> 3. requires in theory only the add of a new IterableIteror class inheriting 
> of Iterator. But making that change visible to the user would require a 
> change in some interface like Mapper and Reducer.
> 4. *Configurable:* If those Interfaces are only used in the ReflectionUtils, 
> it would be enough to deprecate JobConfigurable and to consider it as a 
> particular case of Configurable. Another option would be to deprecate both 
> and to add support in newInstance for passing parameters to constructors.
> *Text:* Text could be an empty class inheriting of TextWritable, in a package 
> like org.hadoop.compat .
