---------------------------------

             Summary: ksck reports WRONG_SERVER_UUID on any RemoteError
                 Key: KUDU-2426
                 URL: https://issues.apache.org/jira/browse/KUDU-2426
             Project: Kudu
          Issue Type: Improvement
          Components: ops-tooling
    Affects Versions: 1.8.0
            Reporter: Andrew Wong
         Attachments: ksck_output.txt

I ran ksck on a relatively recent 1.8.0-snapshot build of kudu and was met with the following:

 

{{WARNING: Errors gathering consensus info for Tablet Server 70f7ee61ead54b1885d819f354eb3405 ([vc1316.halxg.cloudera.com|http://vc1316.halxg.cloudera.com/]:7050): Remote error: could not fetch all consensus info: Not authorized: unauthorized access to method: GetConsensusState}}

 

This is somewhat expected if not running as the kudu user. What was unexpected was that all of the tservers reported WRONG_SERVER_UUID, even though the UUIDs were fine (the ksck report was otherwise healthy). Upon reviewing some ksck-related code, it seems we're taking all remote errors to mean WRONG_SERVER_UUID, which isn't always the case. I've attached a ksck output with the this issue.
