> 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.
