The Murmur3Partitioner range is from -2^63 to 2^63 - 1 (Java's
Long.MIN_VALUE to Long.MAX_VALUE).

Thank you in the output.log I see the line:
INFO 13:36:59,110 This node will not auto bootstrap because it is configured to
be a seed node.
Apparently I changed too much in the cassandra.yaml file. What should the
‘seed’ entry be? From the comments it is a comma separated list of IP
addr
The first thing to check is the log files under /var/log/cassandra, should
give you some hint.
Thanks.

We had puppet scripts which automatically assigned the proper tokens given the

What is the range now? Got a link?

I have installed Cassandra on a Ubuntu Server but I fail to see it with
either:
ps ax
or
netstat -an | grep 9160
I see a file /etc/init.d/cassandra so I am assuming that it should start up.
What else do I need to do? I have edited cassandra.yaml for all the places
that specifically
Ohh lala. Any documentation yet?

Thanks Rob, this makes sense. We only have one rack at this point, so I think
it'd be better to start with PropertyFileSnitch to make Cassandra think that

If you have a lot of data then make sure you run compaction on all nodes

When you read at quorum, a normal read query will be sent to one replica

No it does not exist. Rob and I might start a donation page and give
the money to whoever is willing to code it. If someone would write a
tool that would split an sstable into 4 smaller sstables (even an
offline command line tool) I would paypal them a hundo.

Nope. I think at least once a week I hear someone suggest one way to solve
their problem is to "write an sstablesplit tool".
I'm pretty sure that:
Step 1. Write sstablesplit
Step 2. ???
Step 3. Profit!

Does the "sstablesplit" function exists somewhere ?

@oleg, to answer your last question a cassandra node should never ask
another node for information it doesn't have. it uses the key and the
partitioner to determine where the data is located before ever
contacting another node.

For some of our clusters, we have taken the periodic major compaction
route.
There are a few things to consider:
1) Once you start major compacting, depending on data size, you may be
committed to doing it periodically because you create one big file that
will take forever to naturally compact aga
