Hi everyone
I'm observing a very peculiar type of imbalance and I'd appreciate any help or
ideas to try. This is on cassandra 0.7.8.
The original cluster was 3 machines in the DCMTL, equally balanced at 33.33%
each and each holding roughly 34G.
Then, I added to it 3 machines in the LA data ce
Also, don't use 0.7.4 use the most recent version of 0.7 or 0.8.
Amongst all the other fixes this one is definitely good to have around

As per Jonathans previous comments, the CLI defaults to using the

When using the strategy_options clause you need to specify the options the

If your data is not evenly distributed check the tokens in the ring with

at http://wiki.apache.org/cassandra/Operations#Load_balancing

um. There has got to be something stopping the migration from completing.
Turn the logging up to DEBUG before starting and look for messages from
MigrationManager.java
Provide all the log messages from Migration.java on the 1.27 node

Sounds like you are doing the right thing with regard to consistency.
The error is raised client side when 0 columns are returned for the request. Is
there a chance that some other code is deleting the columns ? Could you add
some logging around the the code to see which columns it fails on ?
Hi,

Hi,
I am newbie to Cassandra. I wanted to load a file present on HDFS to Cassandra
using M/R program.
I am using Cassandra 0.8.2 and Hadoop-0.20.2.
Kindly share me, Is there a document Or sample code available for this?

Hey all,
Thanks to thobbs_ patience in IRC this morning, I got the last of my
questions answered about migrating from v0.6 to v0.8. My cassandra.yaml
is mostly stock out of the box other than IP's, ports (I'm running v0.6
on my workstation at the same time as v0.8), and our cluster name.

Hi,
I experience issues when doing a indexslicequery with multiple expressions if
one of the expressions is about a non index column
I did the equivalent of this example (but with my data) from
http://www.datastax.com/dev/blog/whats-new-cassandra-07-secondary-indexes
Secondary indexes automate
Thanks a lot!
Maybe this should be placed at Cassandra FAQ.
http://wiki.apache.org/cassandra/FAQ#seed has less information.

Is this rule same for N node cluster? Any common practice/formula for seed
number?
Going to use about 10 nodes and extend it in a future.

Anthony,
All I can say is that the steps I outlined below fixed my problem and
allowed me to process 60 million rows of data.

Try 0.8.3
They fixed https://issues.apache.org/jira/browse/CASSANDRA-2968 - and this
produced erroneous records for counters.
Not sure this is exactly yours, but similar.
