[jira] [Created] (KUDU-2778) Explore limitations of multi-master Kudu deployments with more than 3 masters

Alexey Serbin created KUDU-2778:
-----------------------------------

             Summary: Explore limitations of multi-master Kudu deployments with more than 3 masters
                 Key: KUDU-2778
                 URL: https://issues.apache.org/jira/browse/KUDU-2778
             Project: Kudu
          Issue Type: Task
          Components: master
            Reporter: Alexey Serbin


Currently, the recommended limit of Kudu masters in multi-master deployment is by 3 (i.e. no more than 3 masters is recommended): https://github.com/apache/kudu/blob/branch-1.9.x/docs/known_issues.adoc#scale

It would be nice to clarify whether there is anything substantial behind that limit, because as of now the recommendation stems from the fact that all of our multi-master tests and tested deployments are based on that number.  Overall, being able to deploy 5 or more masters in case of bigger clusters makes sense from the HA perspective.
