If you are still having problems can you post the query and the output from
nodetool cfstats on one of the nodes that fails ?
cfstats will tell us if the secondary index was built.

Can you check the logs for errors ? Can you see your schema change in there ?

Doesn't this mean that the read does not reflect the most recent write?
Yes.
A write that fails is not a write.
If it were to have read the newer data from the 1 node and then afterwards
read the old data from the other 2 then there is a consistency problem, but
in the example you give
Removetoken should only be used when removing a dead node from a cluster,
it's a much slower and more expensive operation since it triggers a repair

In the example, I see all ips being used, but our machines are on dhcp so I

I'm playing with cassandra's ruby client written by twitter, trying to

The values that I got are like:

no, the priblem is that jmx listens on 7199, once an incoming connection is
made, it literally tells the other side come and connect to me on these 2
rmi ports, and open up 2 random Rmi ports

That library requires you to serialize and deserialize the data
yourself. So to insert a ruby Float you would

[value].pack('G')
@client.insert(:somecf, 'key', {'floatval' = [value].pack('G')})
and to read it back out:
value = @client.get(:somecf, 'key',
Can you describe your schema again with TierPoint in it?

Hi all,
So nodetool repair has to be run regularly on all nodes. Does anybody
have any interesting strategies or tools for doing this or is everybody
just setting up cron to do it?
For example, one could write some Puppet code to splay the cron times
around so that only one should be running
I use cron. On one box I just do:

A lot easier then managing a bunch of individual crontabs IMHO
although I suppose I could of done it with puppet, but then you always
have to keep an eye out that your repairs
