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 --------------------------------- Resolution: Won't Fix Out of date 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 . -- This message is automatically generated by JIRA.
