Hi,
I am trying to integrate Cassandra with Hadoop. I tried with Cassandra 0.7
rc3 trunk, but failed to do so with following exception,
*java.lang.ClassCastException: [B cannot be cast to java.nio.ByteBuffer
at
org.apache.cassandra.db.marshal.BytesType.compare(BytesType.java:29)*

As Jonathan has told you, Please double check the Timestamp of the column
you are adding the second time. Probably this timestamp is smaller (or
lowerer) than the timestamp given when the deletion happens.

I'm kind of disappointed that adding the -D password file doesn't Just

the patch was simple (NodeCmd and NodeProbe). just testing it now...

Yes, the default GC settings. OpenJDK is b11, from Debian Lenny.

hmm, i added a sleep(1000) between each operation and still see the same
behavior.
but stranger still, if i do the exact same operations via the command line they
work
as expected. and the logs for the two runs look identical to me (aside from
the different keys)

Extend your code to explicitly set the timestamp on the Column in
micro seconds. I think you are just defaulting to 0 and hitting the
condition previously described.

Yeah, double check your are not using a constant on the timestamp, or the
second time you add the same column, such column contains the same timestamp
as the first one (that will be smaller than the one put on the delete
command).
Can you share us your code example?

how are folks customizing the cassandra.yaml for each node in the
cluster. specifically the token and IP address.
with XML i used entities, but i'm not familiar with YAML. does yaml
support the same concept? or any sort of textual substitution?
thx
Funny you should mention that. I just put my half-baked solution to
this problem on github today.
https://github.com/gdusbabek/cassandra-maker. It generates
cassandra.yaml files (and entire config directories too) that are
based on the svn defaults. It should be easy to customize it to fit
your
You can specify the location of cassandra.yaml with a url so you can keep
your configs in one (redundant place) like S3 or generate them on the fly in
a http service...

you're right, i wasn't setting the timestamp on my insert. after fixing that
everything works fine.
thanks,

I've done this before with puppet, but any sort of mainstream
configuration management system should work. There will be some
management overhead in making sure any token changes make it back into
the right server-specific template, but otherwise it's straight
forward.

So, I found a solution, but I think there is a (trivial) bug.
The broken keyspace:
create keyspace KeyspaceDC1 with
replication_factor = 1 and
placement_strategy = 'org.apache.cassandra.locator.NetworkTopologyStrategy'
and
strategy_options = [{DC1:1, DC2:0}];
The fixed keyspace:

Hi,
I am currently having a locally installed Cassandra server running for some

When I try to bring up Tomcat, it fails saying

Yes, that was it. Thanks a lot.
Changed the JMX port in "cassandra.bat", where I didn't look earlier.

Hi guys,
We are trying Cassandra 0.6.8, and could you please kindly tell me which
Hector Java client is suitable for 0.6.8?
The Hector 0.7.0 says it's for Cassandra 0.7.X, and shall we use Hector
0.6.0?
Thanks,
Br
Zhidong
Use 0.6.0-19
