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-108
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.
