Hi,
Here is what I do, starting from 4 0.6.13 nodes with RF 2:
- repair all the nodes
- compact all the nodes
- upgrade to 1.0
- scrub all the nodes
- repair all the nodes
- compact all the nodes
- move one node to a new token
For some requests, I don't get the same result before and after the

Seriously folks - dont make the choice to run 0.6.x build now, that

Hello (5-nodes, RF=3, 32GB RAM, 0.8.6, BOP, 6x2.33Ghz AMD cores)
I'm encountering a weird issue on my CPU-bound workload. Basically I have

seconds. When few were issued it sleeps for 30 seconds

Just solved it. I’m using localhost for the listen_address, 0.0.0.0 for the
rpc_address, and 127.0.0.1 for the seeds.

You can add a DNS entry with multiple IP's or something like a elastic ip
which will keep switching between the active machines. or you can also
write your custom seed provider class. Not sure if you will get a quorum
when there dev's are on vacation :)

In addition to the below i would also think of rebooting one at a time,
just to be safe... folks in my corp are seeing the reboot fail because of
EBS or S3 dependencies while booting the image.

Is there a way to set up a single node cluster without specifying anything
about the specific machine in cassandra.yaml? I've cleared the values from
listen_address and rpc_address, but it complains upon startup that no other
nodes can be seen (presumably because the ip in the seeds doesn't matc

Where did you get this driver? Is it a release, is it from git (and
if so, when/which ID?). What version of Cassandra are yo
Just rebooting a machine with ephemeral drives is ok (it does an os
level reboot). You will also keep the same IP address. If you stop and
then start a machine with ephemeral drives you will lose data.

CompositeType is meant as a comparator to deal with composite column names.
While it is possible to use it as a column value validator, I don't
see any good
use of that.

Hi,
I am using cassandra-jdbc driver and following is my code snip written for
delete a entry from column family.
String query1 = "delete from USER where key=?";
PreparedStatement stmt = con.prepareStatement(query1);
stmt.setString(1, "dinusha");
stmt.execute();
But I am getting following except

You should be able to use the CLI "show schema yourkeyspace" if your
cassandra is recent enough ( >= 0.8 if I remember well. I think it is
better if you are in 0.8.7 because this command was fixed a couple of times
in 8.6 and 8.7).
You can put the "show schema" command into a file and call it with
