> For the storing of tf-idf in hbase ( lucene-hbase project) we need to scan
> the keys across the table and retrieve columnar values. Quite an amount of
> logic can be reused from TableRecordReader for the purpose.
> - Refactored TableRecordReader ( from being a protected inner class to a
> public class outside )
> - Created an impl class , that does the actual work, without the dependency
> on hadop.mapreduce.* packages ( RecordReader) while retaining the
> implementation that can be reused across libraries.
> Do the same thing for .mapred. and .mapreduce. packages.
> Let me know the thoughts on the same.
