    Comment: was deleted

(was: Hi,[+Konstantin Shvachko+|https://issues.apache.org/jira/secure/ViewProfile.jspa?name=shv],If
I understand correctly,We should start up observerNode and make it work in an auto-failover
environment, and  ZKFC failover controller will need to recognize the observer state. Is
it?

or ObserverNodes can automatic failover to SBNs.

I'm doing something about failover,Maybe you can assignee this issue to me,thank you very
much.)
