> add concrete common implementations of CombineFileInputFormat

> Key: MAPREDUCE-5069
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5069
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: mrv1, mrv2
> Affects Versions: 2.0.3-alpha
> Reporter: Sangjin Lee
> Priority: Minor
> Attachments: MAPREDUCE-5069-1.patch, MAPREDUCE-5069-2.patch,
> MAPREDUCE-5069.patch
>
>
> 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.
