> CombineFileInputFormat is abstract, and its specific equivalents to
> TextInputFormat, SequenceFileInputFormat, etc. are currently not in the
> hadoop code base.
> These sound like very common need wherever CombineFileInputFormat is used,
> and different folks would write the same code over and over to achieve the
> same goal. It sounds very natural for hadoop to provide at least the text and
> sequence file implementations of the CombineFileInputFormat class.
