> 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.
