          Components: clients
    Affects Versions: 2.6

In some cases after the coordinator change, the client node can be failed before it can establish a connection to another server from the cluster.

It looks like a race condition.

Steps to reproduce:

1. Start server A.
2. Start client.
3. Start server B.
4. Stop server A.

If add Thread.sleep(10000) between (3) and (4) then the client node won't be disconnected from the cluster.

Reproducer is attached [^ClientDisconnectedTest.java].
