> Today HFileReader has the hardcoded key field name for the schema. This key 
> field is used by HFileWriter, HFileDataBlock for HFile key dedupliacation 
> feature. When users want to use the HFile format, this hard coded key field 
> name can be preventing the usecase. We need a way to pass in the 
> writer/reader/query configs to the HFile storage layer so as to use the right 
> key field name.
