> This is a follow up for HBASE-18186.
> FileNotFoundException while scanning from a primary region replica can be
> indicative of a more severe problem. Handling them silently can cause many
> underlying issues go undetected. We should either
> 1. Hard fail the regionserver if there is a FNFE on a primary region replica,
> OR
> 2. Report these exceptions as some region / server level metric so that these
> can be proactively investigated.
