> want InputFormat for zip files
> ------------------------------
>
> Key: HADOOP-1824
> URL: https://issues.apache.org/jira/browse/HADOOP-1824
> Project: Hadoop
> Issue Type: New Feature
> Components: mapred
> Affects Versions: 0.15.2
> Reporter: Doug Cutting
> Attachments: ZipInputFormat.patch
>
>
> HDFS is inefficient with large numbers of small files. Thus one might pack
> many small files into large, compressed, archives. But, for efficient
> map-reduce operation, it is desireable to be able to split inputs into
> smaller chunks, with one or more small original file per split. The zip
> format, unlike tar, permits enumeration of files in the archive without
> scanning the entire archive. Thus a zip InputFormat could efficiently permit
> splitting large archives into splits that contain one or more archived files.
