> HIFIO is currently in PR (  and as per discussion
we'd like to check HIFIO in as-is, then unify the two since they share a lot of code. 
> [] has mentioned: "the FileInputFormat reader gets to call some special
APIs that the
> generic InputFormat reader cannot -- so they are not completely redundant. Specifically,
FileInputFormat reader can do size-based splitting." 
> Dan recommended: "See if we can "inline" the FileInputFormat specific parts of HdfsIO
inside of HadoopInputFormatIO via reflection. If so, we can get the best of both worlds with
shared code." 
> This seems reasonable to me.
