if you are looking for all tokens assigned, 'nodetool info -T' might help.

Hi,
I have a fresh 1-node C* 2.0 install with a demo keyspace created with the
SizeTiered compaction strategy.
I've noticed that in the beginning this keyspace has just one SSTable:
demodb-users-jb-1-Data.db
But as I add more data to the table and do some flushes, the # of SSTables
builds up. Af

I've been running into a variety of tricky to diagnose problems recently
that could be summarized as "bootstrap & related tasks fail without
extra hacky sleep time".
This is a sample edited log file for bootstrapping a node that captures

Hi all,
We are using the Ruby gem wrapper for Cassandra:
"cassandra-cql"
I was wondering if anyone has come across this error before:

It is difficult to imagine how these config changes might be related.

I haven't used VMWare but it seems odd that it would lock up the ntp port. try
"ps aux | grep ntp" to see if ntpd it's already running.

Hi all,
I want to move to new Cassandra version and use Java DataStax CQL client
with it. For now on I've been using Hector as a Java client and
cassandra-unit to run junit test.
What should I use to test the code now? Is there a special library for
testing code using Datastax driver?

I had similar issue (reported many times here, there's also a JIRA
issue, but people reporting this problem were unable to reproduce it).
What I can say is that for me the solution was to run major compaction
on the index CF via JMX. To be clear - we're not talking about
compacting the CF that
On a 2-node cluster with replication factor 2, I have a column family with

Every now and then, I notice that a lookup of the record through the index

do a lookup by row key, the record is fo
Hello all,
we are planning a Cassandra 1.2 installation at a client site; the
client will run operations themselves and based on their IT team's
experience they are more inclined towards running Cassandra nodes on
Windows servers, however given proper arguments they would also consider
using linux

I didn't notice your message at first.. Well this seems like a real cause
