Duo Zhang commented on HBASE-18786:
-----------------------------------
I'm +1 on remove the logic
Let me help linking the related issues.
The problem should be gone after we write a compaction marker before doing the
final deletion of HFiles and also replay the compaction marker when failover.
AFAIK this is the only possible(no harm) way to produce FNFE with no data loss.
> FileNotFoundException should not be silently handled for primary region
> replicas

> 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.
