David Alves commented on KUDU-1927:
-----------------------------------
Well if it's a rare race it might go unnoticed and happen in prod, at which
time a DCHECK wouldn't help. In the specific case I was looking at such a race
was possible (though I don't think it actually happened).
At the very least we should change it to CHECK, if you agree.

> Key: KUDU-1927
> URL: https://issues.apache.org/jira/browse/KUDU-1927
> Project: Kudu
> Issue Type: Bug
> Components: master, security
> Affects Versions: 1.3.0
> Reporter: Todd Lipcon
>
> MasterServiceImpl::ConnectToMaster currently has a TODO that there might be a
> case where a client issues the RPC exactly as a leader is becoming active.
> The worry is that it may return a response indicating LEADER status, but
> without the ability to issue a key.
