Hi, Hector does not retry on a down server. In the unit tests where you have just one server, Hector will pass the exception to the client.

Can you tell us please what your test looks like ?

I only saw this error message when all Cassandra nodes are down.

How you get the Cluster and how you set the hosts?

We had this one, even tho in the hector documentation it says that it
retry s failed servers even 30 by default, it doesn't.

Once we explicitly set it to X seconds, when ever there is a failure,
ie with network (AWS), it will retry and add it back into the pool.
