[GitHub] [ozone] errose28 opened a new pull request #2080: HDDS-5023. Datanodes should always use MLV 0 when no VERSION file is present.

errose28 opened a new pull request #2080:
URL: https://github.com/apache/ozone/pull/2080


   ## What changes were proposed in this pull request?
   
   Since older versions of the code did not have a VERSION file for datanodes, they should assume they are pre-finalized and use layout version 0 by default when no VERSION file is present. If they are being started fresh (not part of an upgrade), SCM will tell them to finalize and they will move to match SCM's layout version after one heartbeat.
   
   ## What is the link to the Apache JIRA
   
   HDDS-5023
   
   ## How was this patch tested?
   
   Added fix to HDDS-4181 acceptance tests, and the MLV tests there verified that pre-finalize datanodes are using the correct MLV when pre-finalized.
