             Summary: HddsVolume mixes ChunkLayOutVersion and DataNodeLayoutVersion
                 Key: HDDS-2693
                 URL: https://issues.apache.org/jira/browse/HDDS-2693
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
            Reporter: Attila Doroszlai
            Assignee: Attila Doroszlai


{{HddsVolume}} [initializes {{layoutVersion}} using latest {{ChunkLayOutVersion}}|https://github.com/apache/hadoop-ozone/blob/1d56bc244995e857b842f62d3d1e544ee100bbc1/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/volume/HddsVolume.java#L268].  But when writing the same info to file, it [verifies {{layoutVersion}} matches the latest {{DataNodeLayoutVersion}}|https://github.com/apache/hadoop-ozone/blob/1d56bc244995e857b842f62d3d1e544ee100bbc1/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/volume/HddsVolume.java#L292-L293].  To satisfy the condition {{ChunkLayOutVersion}} and {{DataNodeLayoutVersion}} have to be in sync, which means only one of them is necessary.  I think the intention was to use {{DataNodeLayoutVersion}} in both cases, as {{ChunkLayOutVersion}} is for key-value container internal structure.
