To recap the problem,
1.1.6 on SSD, 5 nodes, RF = 3, one CF only.
After data load, initially all 5 nodes have very even data size (135G, each). I
ran nodetool repair -pr on node 1 which have replicates on node 2, node 3 since
we set RF = 3.
It appears that huge amount of data got transferred.
Make sure you are setting the discovery type to ring describe or token
aware. This is different from the connection pool type, which can also be
token aware.

I use astyanax 1.56.18 with cassandra 1.1.5. Everything works as supposed
to. What does ThreadPoolMonitor report?

Even I am facing a similar issue. I am using Bulkoutput format for loading data
from Hadoop to Cassandra.
All I need is to set the storage_port explicitly in my job/program.
Can anyone help me in setting the storage_port configuration parameter from my
java program?

If your project isn't meant to go in production immediately and you want to
use Cassandra 1.2+, you can give a try to DataStax' new Java driver which
is available at https://github.com/datastax/java-driver
Just a snapshot for now. A 1.0 release is expected for late March,
meanwhile we'll iterate ov

Just a quick question about the attributes exposed via JMX. I have some doc [1]
but it doesn't help about CF beans.
The "BloomFilterFalseRatio", is that the ratio of found vs missed, or the ratio
of false positive vs the number of tests, or something else ?

No, I don't mean 2 instances.
Cassandra 1.2.0 has 2 completely separate client server: the thrift one and
the native protocol one. You can start those independently. So, on the same
instance you can have either just thrift, just the native protocol, both of
them or none of them (though that latter
Any suggestions?
Once i enable *native_transport_port: 9042*, it will not start cassandra
thrift automatically, Even if *start_rpc: true* ? Or it should start
listening to both ports?

Hi Ben,
Thanks for the tip I will certainly check it out. I really appreciate the
information!

For Beginners on any new open source, it is always good to have atleast
some sort of comments!

Means start 2 instances , 1 for thrift based access and another for native?
Of course on different port.

Well, the cassandra-cli uses the thrift protocol, so it will not work is
you use start_rpc: false.
Whether you start the binary protocol server has no real impact as
Cassandra is fine starting both server (as long as you don't set the same
port for both for obvious reasons).
Obviously, if you point
Then only possible way is via creating own java program to connect/execute?
And then restart again in Thrift mode to connect via cqlsh/cassandra-cli ?

OK.I guess that's why there is a need of class/method level java comments.

Is this a valid assumption that cassandra-cli will not work, if Cassandra
server is getting started by enabling CQL binary protocol?
