If we further increase the limit of ulimt, would it
routing more traffic to it?
So shouldn't I see more network in on that node in the AWS console ?
It seems that each node is recieving and sending an equal amount of data.
What value should I use for dynamic-snitch-badness-threshold to give it a
try ?

I've a running cluster (3 nodes) with release version 1.2.0-beta2, and I've
successfully added/removed nodes to this cluster in the past.
I'm trying to add a new node to the cluster with release version 1.2 rc1,
but it seems like other peers are refusing to connect, these are the
exceptions:

Hello,
Thank you very much for your quick responses.
Initially we were thinking the same thing, that an explanation would
be that the wrong node could be down, but then isn't this something
that hinted handoff sorts out? So actually, Consistency Level refers
to the number of replicas, not the
Thanks for the clarification -- it doesn't sound too bad for my purposes.
As per your suggestion, I've created an issue:

Don't run with a replication factor of 2, use 3 instead, and do all reads

That way, if a single node is down, all your operations will complete. In
fact, if every third node is down, you'll still be fine and able to handle
all requests.

The Cassandra team is pleased to announce the release of Apache Cassandra
version 1.1.8.
Cassandra is a highly scalable second-generation distributed database,

Hi,
Let's imagine a cluster of 6 nodes, 5 on rack1 and 1 on rack2.

Yes, but they will get compacted away again unless the patch is there.
it's a small patch so you should be able to apply it easily enough if you need
a fix ASAP.

Yes, Customer is the keyspace.
I tried giving the column family name as well and getting same error.
Also tweaked by changing the slash from '\' to '/' or '\\'.
Any other ideas?

Sounds about right, i've done similar things before.
Some notes…

If you are using Levelled Compaction it is probably easier to set the ulimit to
unlimited.

In the case without CQL3, where I would use composite columns, I see how
this sort of lines up with what CQL3 is doing.
I don't have the ability to use CQL3 as I am using pycassa for my client,

Yup.
