Will Berkeley commented on KUDU-2309:
-------------------------------------
This can also result in some alarming-looking situations, such as /masters
showing two leaders. This could happen if encryption is disabled and one of the
masters is permanently lost, then a new singleton master is start at the same
address. Screenshot attached.

If encryption is enabled then the multimaster members will have errors trying
to get the registration info of the singleton.
> /masters can show the wrong list of masters

> Key: KUDU-2309
> URL: https://issues.apache.org/jira/browse/KUDU-2309
> Project: Kudu
> Issue Type: Bug
> Components: ops-tooling
> Affects Versions: 1.6.0
> Reporter: Will Berkeley
> Priority: Major
> Attachments: twoleaders2309.png

>
> Consider the following steps:
> # Three masters are started with UUIDs A, B, and C.
> # A is shut down and its data deleted. A new master with UUID D is started
> on the same machine.
> After this, visiting /masters on B or C should show A, B, and C as the
> registered masters, since they are the masters in B and C's quorum. D's
> /masters should just show D. However, right now we show B, C, D in all three
> /masters pages.
