FileNotFoundException should not be silently handled for primary region replicas

Details

    • Reviewed
    • FileNotFoundException opening a StoreFile in a primary replica now causes a RegionServer to crash out where before it would be ignored (or optionally handled via close/reopen).

    Description

      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.
