             Summary: Add a StorageState to represent insufficient privilege
                 Key: RATIS-1654
                 URL: https://issues.apache.org/jira/browse/RATIS-1654
             Project: Ratis
          Issue Type: Improvement
            Reporter: Wei-Chiu Chuang


If raft is unable to initialize a storage due to insufficient privlege (e.g. the directory is owned by root and raft is run by ozone user) it throws a confusing error:

Instead of NON_EXISTENT it would be less ambiguous to add a INSUFFICIENT_PRIVILEGE state.
