Hi,
I have just started the process of upgrading Cassandra from 0.7.2 to 0.8.4,
and I am facing some issues with embedded cassandra that we utilize in our
application.
With 0.7.2, we define our keyspace in cassandra.yaml and use Hector to give
us an embedded cassandra instance loaded with schema
ok, it seems that the '[ ]' should not be there now

I pulled the latest code from
github 3e77792d31344be0253c89355c1d96ffe03c0659
and used my old commands to create a regular KS, and it failed.
quick debugging shows that the client hits an NPE somewhere.
am I missing some new mandatory args ?
Thanks

I ran into this problem today. It's common enough that it shows up in google,
but not common enough to have a documented resolution, so here's one.

0.8.5 is being voted on now on the dev list. I'd encourage you to test it.
I do not recommend running trunk.

Jonathan, do you know when 0.8.5 will be released? We are looking at a
production deployment soon and this fix is something that we would need.
Alternatively, what is the stability of the trunk for a production
deployment.

Since we finally fixed this issue, I thought I'd document the
solution, with the hope that it makes it easier for others who might
run into it.
During the time this issue was occurring Anthony Ikeda reported a very
similar issue, although without the strange pattern of occurrences we
saw:

Hi,
Is there any suggested way of calculating number of nodes needed based on data?
We currently have 6 nodes (each has 8G memory) with RF5 (because we want to be
able to survive loss of 2 nodes).
The flush of memtable happens around every 30 min (while not doing compaction),
with ~9m serializ
Thanks for sharing the info.. though I contacted datastax using contact form
but no reply yet after more than a week.
Probably I need to contact Ben directly.

I also have used datastax with great success (same disclaimer).
A specific example:

fault as I believe they could have worked me in within a day. I
We use Datastax (http://www.datastax.com) and we have been very happy
with the support we've received.
We haven't tried any of the other providers on that page, so I can't
comment on them.

What is it?
There are many great articles about building secondary Cassandra indexes
such as http://www.anuff.com/2011/02/indexing-in-cassandra.html. In a
nutshell, index building boils down to turning a single insert into multiple
inserts to support diff

move tokens from your empty nodes into different position in ring; split
your full nodes in half. ring will then look like: owns 14% 14% 14%
rest of ring.
Hi All,
I am using Cassandra-0.7.8 on cluster of 4 machines. I have uploaded some files
using Map/Reduce.
It looks files got distributed only among 2 nodes. When I used RF=3 it had got
distributed to equally 4 nodes on below configuration.
Here are some config info's:

Sorry for the newbie question but I failed to find a clear answer.
Can CQL be used to query a schema-less column family? can they be indexed?
That is, query for column names that do not necessarily exist in all
rows, and were not defined in advance when the column family was
created.
Thank you
Hi Jonathan
Thanks for the explanation

I'm pleased to announce the release of Cassandra 0.7.9.
0.7.9 contains a number of important bug-fixes (full list here[1]),
and should be an easy upgrade from previous 0.7 releases.
Source and binary distributions are available from the Downloads
