> HIFIO is currently in PR (https://github.com/apache/beam/pull/1994)  and as per discussion in https://lists.apache.org/thread.html/803857877804165e798cf31edf079e6603eb9682b7690d52124c31e7@%3Cdev.beam.apache.org%3E, we'd like to check HIFIO in as-is, then unify the two since they share a lot of code. 
> [~dhalperi@google.com] 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.
