Thanks Robert, Is there a workaround, as in our test setups we keep
dropping and recreating tables.

Hello all,
I’m trying to collect and organize Cassandra applications for educational
purposes. I’m hoping that by collating these applications in a single place,
new users will be able to get up to speed a bit easier. If you know of a great
application (should be open-source and preferably up t

Nope! It's disabled.

I have to reply to myself, since there were no helpful responses.
Perhaps these notes can help other people from pulling their hair out.
When installing the datastax-agent on EL6, it is required to do a bunch
of things to correct a bunch of stuff.
[] yum install mx4j log4j datastax-agent -

Yes. Generally, vnodes
Perhaps I should clarify my question. Is this possible / how might I
accomplish this with cassandra?

Yep! With no change in result. I get the exact same error message running
as a non-privileged user.

I found a lot of documentation about the read path for key and row caches, but
I haven't found anything in regard to the write path. My app has the need to
record a large quantity of very short lived temporal data that will expire
within seconds and only have a small percentage of the rows acce

Hi Marcin,
Thanks! I'm running the bash shell. And for some reason it also looks like
bash does understand 'exec'.
[root@beta:~] #echo $SHELL
/bin/bash
[root@beta:~] #exec
Why it suddenly looses that understanding when it runs the cassandra start
script, I have no clue.
I even tried changing
Hi Marcin,
You are correct that I am using Vagrant. Sorry for not specifying that.
OMG you are correct. I spent about an hour over the weekend trying to
figure out what was going on. I got confused because "listen_address"
is also set to node[:ipaddress], and listen_address was always set

Hi Clint,
I'm guessing you are using vagrant. The thing is cassandra-chef-cookbook
use template cassandra.yaml.erb, where you can find:
"broadcast_address: <%= node[:cassandra][:broadcast_address] %>" which in
turn is equal to "node[:ipaddress]".
Value of node[:ipaddress] depends on how do you con
Hi Tim,
exec is a shell builtin command, what kind of shell do you use?
Please run:
$ echo $SHELL

Thanks for your response. I understand what you are saying with
regard to the load balancing. I posted my question to the DataStax

your assumption about 256 tokens per node is correct.
as for you second question, it seems to me like most of your assumptions
are correct, but I'm not sure I understand them correctly. hopefully
someone else can answer this better. tokens are a property of the cluster
and not the keyspace. the fi
