Summary: 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
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.
