What git sha are you on? I'm absolutely not hitting that break point running
that exact test. I'm at 091889cf79e15909963b6fad6c0a5394a34764bc. The only
local changes I have are to comment out the calls to the other tests in that
class so that testAddAndDeleteReplica is the only test method run.
Nor am I seeing this log message in the test logs:
{code}
public ZkWriteCommand addReplica(ClusterState clusterState, ZkNodeProps
message) {
log.info("createReplica() {} ", message);
{code}

> ZkController.publishAndWaitForDownStates() occurs before overseer election.
> That means if there is currently no overseer, there is ironically no one to
> actually service the down state changes it's waiting on. This particularly
> affects a single-node cluster such as you might run locally for development.
> Additionally, we're doing an unnecessary ZkStateReader forced refresh on all
> Overseer operations. This isn't necessary because ZkStateReader keeps itself
> up to date.
