Description

If root file for a Reference is missing, takes a while to figure it. Master-side says failed open of Region. RegionServer side it talks about FNFE for some random file. Better, dump out Reference data. Helps figuring what has gone wrong. Otherwise its confusing hard to tie the FNFE to root cause.
