David Mollitor updated KUDU-3226: --------------------------------- Description: 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. This happened for me with {{kudu ksck}} but there may be other candidates as well. was: I recently accidentally included a list of masters where I fat-fingered the host names and included the same node twice.
