> Refactor InputFormat and OutputFormat for Hive
> ----------------------------------------------
>
> Key: HIVE-1133
> URL: https://issues.apache.org/jira/browse/HIVE-1133
> Project: Hadoop Hive
> Issue Type: Improvement
> Affects Versions: 0.6.0
> Reporter: Zheng Shao
>
> Currently we ran into several problems of the FileInputFormat/OutputFormat in Hive.
> The requirements are:
> R1. We want to support HBase: HIVE-806
> R2. We want to selectively include files based on file names: HIVE-951
> R3. We want to optionally choose to recurse on the directory structure: HIVE-1083
> R4. We want to pass the filter condition into the storage (very useful for HBase, and indexed data format)
> R5. We want to pass the column selection information into the storage (already done as part of the RCFile, but we can do it better)
> We need to structure these requirements and the code structure in a good way to make it extensible.
