Hi,
I have a keyspace called Index.
I am trying to create it when I create a new cluster from the script that
was created on the old cluster.
create keyspace Index
with placement_strategy = 'SimpleStrategy'
and strategy_options = {replication_factor : 3
and durable_writes = true;

Hi All,
I'm trying to start up Cassandra 1.0.5 on a Cent OS 6 machine. I installed JNA
through yum and made a symbolic link to jna.jar in my Cassandra lib directory.
When I run "bin/cassandra -f", I get the following:
INFO 09:14:31,552 Logging initialized
INFO 09:14:31,555 JVM vendor/versio
Was't that on the 1.0 branch ? I'm still running 0.8x ?
@Peter: investigating a little more before answering. Thanks

Subject: Cannot Start Cassandra 1.0.5 with JNA on the CLASSPATH
Hi All,
This is quite a different subject and the question has already been asked a
few days ago (December, 1) :
http://www.mail-archive.com/user@cassandra.apache.org/msg19083.html
Anyways, you can test it by yourself changing the name of the column
family. I don't know more about it by myself.

Possible, but unlikely. See
https://issues.apache.org/jira/browse/CASSANDRA-3537 for an example of
a "memory leak" that wasn't.
I didnt get the point. I have slowly increasing memory load on node, no
flushable memtables. How it could not be memory leak? Also running
nodetool upgradesstables
Hi Sylvain,
"Writes under the same row key are atomic (*even across column families*)
in the
sense that they are either all persisted or none are."
Is this new feature for 1.x, or it also applies to previous version of
Cassandra?

Hi Peter,
I'm going to mix the response to your email along with my other email from
yesterday since they pertain to the same issue.
Sorry this is a little long, but I'm stomped and I'm trying to describe
what I've investigated.
In a nutshell, in case someone has encountered this and won't read it

Interesting development : I changed the maximum size of the batches in
"Process A" to get them to go from about 90 per execute() to about 35. All
the weird 28s/38s maximum execution times are gone, all timeouts are gone
and everything is zipping along just fine. So moral of the story for me is

Sounds like https://issues.apache.org/jira/browse/CASSANDRA-3558 and the
other tickets reference there.

Hi,
We are currently testing cassandra in RHEL 6.1 64 bit environment
running on ESXi 5.0 and are experiencing issues with data file
corruptions. If you are using linux for production environment can you
please share which OS/version you are using?
thanks

Hello,
When I use nodetool cfstas, I see read/write for both keyspace and column
family. I assume both number are counted across the ring, but I saw different
read/write counts showed on one node comparing to other 7 nodes.
node 1,2,4-8:
Keyspace: ks
Read Count: 44285565

Briefly, it's based on timestamp conflict resolution. This may be a
good resource:

Individual node.
Also note that the CF level counts will refer to local reads/writes
submitted to the node, while the statistics you get from StorageProxy
(in JMX) are for requests routed. In general,

Hi,
This is my first post, so first of all - thanks to Cassandra authors and
community for their excellent job!
Now to my question... I need a plan for transition from SimpleStrategy
to NetworkSopologyStrategy (as I have to add two servers from remote

I have a dead node I need to remove from the cluster so that I can rebalance
among the existing servers (can't replace it for a while).
I used nodetool removetoken and it's been stuck in the "leaving" state for over
a day now. I've tried a rolling restart, which kicks of some streaming for a
