> SequenceFile and MapFile need cleanup to remove redundant constructors

> Key: HADOOP-6856
> URL: https://issues.apache.org/jira/browse/HADOOP-6856
> Project: Hadoop Common
> Issue Type: Improvement
> Components: io
> Reporter: Owen O'Malley
> Assignee: Owen O'Malley
> Fix For: 0.22.0
>
> Attachments: h-6856.patch, h-6856.patch

>
> Currently there are 2 public SequenceFile.Reader constructors, 3 public
> SequenceFile.Writer constructors, 9 public SequenceFile.createWriter, 2
> public MapFile.Reader constructors, and 8 public MapFile.Writer constructors.
> All of with various historical combinations of parameters that don't cover
> the entire space.
> All of this makes it *very* difficult to add new optional parameters to
> SequenceFile and MapFile.
> I'd like change to the style of FileContext.create with option parameters.
> I'll implement one public SequenceFile.Reader constructor and one public
> SequenceFile.createWriter and implement all of the current variants based on
> those two. I'll do the same for MapFile.Reader and MapFile.Writer including
> passing parameters down to the underlying SequenceFile.
