I've recently added compaction rate (in bytes / second) to my monitors for
cassandra and am seeing some odd values. I wasn't expecting the values for
TotalBytesCompacted to sometimes decrease from one reading to the next. It
seems that the value should be monotonically increasing while a server i
I am using CQL 3 and trying to execute the following,

i believe the system keyspace keeps track of the cluster topology.
even though you changed info in yaml, the system keyspace still knows
about the other nodes. remove the system keyspace files from data dir
and try again

We've been using 1.1.5 for a few weeks now and it's been stable for our
uses. Also, make sure you upgrade to a more recent version of 1.0 branch
before going to 1.1. Version 1.0.7 was released before 1.1 and there are
upgrade-path fixed applied to 1.0 after that. Our upgrade path was 1.0.9
-> 1.
In 1.1.5 file descriptor leak was fixed. In my case it was critical.
Nodes went down every several days. But not everyone had this problem.
Thank you,
Andrey

Hello,
We are planning to upgrade from version 1.0.7 to the 1.1 branch. Which is
the stable version that people are using? I see the latest release is 1.1.5
but maybe it's not fully wise to use this. Is 1.1.4 the one to use?
Cheers,
Alex
What if gc_grace_seconds is pretty low, say 2 mins, what happens with
nodetool repair ?
That wiki page below points at a bug that has been fixed long ago. Is
it still an issue if you don't run a repair within gc_grace_seconds ?

I guess that the other nodes still gossips about the removed node. The
node isn't removed from gossiper in the cluster until some amount of
time have elapsed. My guess is that you haven't changed the cluster_name
property in the cassandra.yaml on the removed node.

When restoring a backup for the entire cluster my understanding is that
you must shutdown the entire cluster and then restore the backup and
then start up all nodes again.
