Yes it does, the stack trace is in the first thread. I did not try to
create CF (was trying to enable it in cassandra.yaml), I have an existing
CF and wanted to use compression for inter-node communication. When I
enable snappy compression (in yaml) I get the error and cassandra quits. I
figured th
IIRC there is a test for snappy when the node starts does that log an error ?
And / or can you create a CF that uses snappy compression (it was the default
for a while in 1.2).

Hello,
I was able to run WordCount in $CASSANDRA_HOME/examples/hadoop_word_count and
the Cassandra version is 2.0.2
So when I start the word_count, the actual process is a Java -cp . Is there
a Jobtracker started by the Cassandra or how is the wordcount mapreduce job
run. Is there a task t

Astyanax and/or the DS Java client depending on your use case. (Emphasis on
the "and" - really no reason you can't use both - even on the same schema -
depending on what you are doing as they both have their strengths and
weaknesses).
To be clear, Hector is not going away. We are still accepting p
Nate,
(slightly OT), what client API/library is recommended now that Hector is
sunsetting? Thanks.

You basically want option (c). Option (d) might work, but you would be
bending the paradigm a bit, IMO. Certainly do not use dedicated column
families or keyspaces per tennant. That never works. The list history will
show that with a few google searches and we've seen it fail badly with
several cli
Thats it! I knew NetworkTopologyStrategy goes through racks when writing,
but didn't consider that the first one will most likely be used.
I'll re-arrange my nodes to be a,b,c,a,b,c

The problem is that NetworkTopologyStrategy will try to pick nodes that
have a different rack when going around the ring, so the second node in
each rack always gets skipped unless it was the first node picked. Your
nodes is eu-west go a,a,b,b,c,c but they should be a,b,c,a,b,c.

Hello Katriel,
Are you using replication factor 3? So it seems that in us-east it's all
fine with each machine having 100% of the data. The problem is in eu-west
where you have unbalanced nodes. You should rearrange the tokens in that
eu-west DC.
Check e.g. this token calculator to calculate good
Hello list,
I have a problem with my cluster ownership not being as expected.
I have 2 DC cluster using NetworkTopologyStrategy on and
EC2MultiRegionSnitch with cassandra 1.1.5. My placement strategy for all
keyspaces is: {eu-west: 3, us-east:3 }, and I have 6 nodes in eu-west and 3
in us-east.

I'm having the same problem, after upgrading from 1.2.3 to 1.2.10.
I can remember this was a bug that was solved in the 1.0 or 1.1 version
some time ago, but apparently it got back.
A workaround is to delete the contents of the saved_caches directory before
starting up.
