Assignee: Abhishek
> Validate List of Masters for kudu ksck
> --------------------------------------
>
> Key: KUDU-3226
> URL: https://issues.apache.org/jira/browse/KUDU-3226
> Project: Kudu
> Issue Type: Improvement
> Reporter: David Mollitor
> Assignee: Abhishek
> Priority: Minor
> Labels: beginner, newbie, trivial
>
> I recently accidentally included a list of masters where I fat-fingered the
> host names and included the same node twice.
> I got some stack trace and an error message about duplicate keys inserted
> into a map. I eventually figured out what I did wrong, but the error
> condition was not super helpful.
> Please add an early validation step that explicitly captures this conditions
> and provides a helpful error message that includes the name of the host name
> which was duplicated on the command line.
