    Description

      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: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.
