We are using version 1.2.4 and it is difficult to shutdown the embedded
version. But you don't have to. Just check in each test setup method if
embedded Cassandra is already running and start it if necessary. Than
create keyspaces/tables in setup methods and drop them in teardown methods.
For us th
As far as I know there is nothing hard coded in Cassandra that kicks in
every 4 hours. Turn on GC logging, maybe dump the output of jstats to a
file and correlate this data with the Cassandra logs. Cassandra logs are
pretty good in telling you what is going on.

If you lose RF + 1 nodes the data that is replicated to only these nodes is
gone, good idea to have a recent backup than. Another situation is when you
deploy a bug in the software and start writing crap data to Cassandra.
Replication does not help and depending on the situation you need to
restore
We just migrated a Cassandra cluster on EC2 to another instance type. We
replaced one server after another, this creates problems similar to what
you describe.
We simply stop Cassandra, copy the complete data dir to an EBS volume,
terminate the server, launch another server with the same IP, copy
ause ...
and we put .setConnectTimeout(2000) and we increased the other values from
Astyanax pool and our App worked ...
basically I think our initial problem was Amazon latency that was to high,
so we changed our pool configuration and the things worked fine ...
thank all for the help !

"RandomPartitioner", and maybe the correct
could be "Murmur3Partitioner" when we use Hadoop (I am not sure too) ... if
that is true I got a problem because I can't change the partitioner with
Priam (I think it only works with RandomPartitioner) ...

I don't know what exactly this message means and how to solve the problem
... I am using Priam for manager my cluster in Cassandra over Elastic
Map/Reduce on Amazon ...
Any hint helps ...
Thanks,

Tables and removed
them during
a node restart. On some nodes compaction is working for the moment but
there are likely
more corrupt datafiles and than I would be in the same situation as before.
So I still need some help to resolve this issue!

Any help to resolve this situation would be greatly appreciated.
Thanks

Marcelo,
das vezes q tive este problema geralmente era porque o valor UUID sendo
tratado para o cassandra não correspondia a um valor "exato" em UUID, para
isso utilizava bastante o UUID.randomUUID() (para gerar um UUID valido)
e UUID.fromString("081f4500-047e-401c-8c0b-a41fefd099d7") - este para
k for you.

Yeah that certainly seems to be the way forward, thanks.
Made adjustments but I'm still coming up short, the set strategy class
method has no javadoc and I'm getting a
InvalidRequestException(why:org.apache.cassandra.locator.RackUnawareStrategy
)
Am I doing thi
ansport(new TSocket(host, port));
Cassandra.Client cassandraConn = new Cassandra.Client(new
TBinaryProtocol(transport));
transport.open();
It is now Framed transport ;-)
Hope that helps

Hi everyone.
I'm having a bit of a problem getting started with 0.7
I had 0.6.4 working and I want to start checking out 0.7, I can't figure out
how to create keyspaces to even get started.
Can anyone also give me a little info on secondary index's, their purpose
and use
