Jonathan Ellis commented on CASSANDRA-4066:
-------------------------------------------
It wouldn't have; those who were bit by the linux kernel bug had worse problems
than this to worry about.
> Cassandra cluster stops responding on time change (scheduling not using
> monotonic time?)

> Key: CASSANDRA-4066
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4066
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Linux; CentOS6 2.6.32-220.4.2.el6.x86_64
> Reporter: David Daeschler
> Assignee: Brandon Williams
> Priority: Minor
> Labels: gossip
> Fix For: 1.1.1

> The server installation I set up did not have ntpd installed in the base
> installation. When I noticed that the clocks were skewing I installed ntp and
> set the date on all the servers in the cluster. A short time later, I started
> getting UnavailableExceptions on the clients.
> Also, one sever seemed to be unaffected by the time change. That server
> happened to have it's time pushed forward, not backwards like the other 3 in
> the cluster. This leads me to believe something is running on a
> timer/schedule that is not monotonic.
> I'm posting this as a bug, but I suppose it might just be part of the
> communication protocols etc for the cluster and part of the design. But I
> think the devs should be aware of what I saw.
> Otherwise, thank you for a fantastic product. Even after restarting 75% of
> the cluster things seem to have recovered nicely.
