    Details

    • Type: Sub-task
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 1.4.0, 1.3.3, 2.0.0
    • Component/s: regionserver, Scanners
    • Labels:

    • Release Note:
      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.
