Have you tried to change: me.prettyprint.cassandra.service.CassandraHostConfigurator#retryDownedHostsDelayInSeconds ?

Hector will ping down hosts every xx seconds and recover connection.

I just got this error ": All host pools marked down. Retry burden pushed out to client." in a few clients recently, client could not  recover, we have to restart client application.  we are using hector.

At that time we did compaction  for a CF, it takes several hours, server was busy. But I think client should recover after server load was down.

Any bug reported about this? I did search but could not find one.
