Right, at that point either, cassandra-cli or cqlsh will not see any
endpoint. Only after you drop the keyspace and re-create it with
cassandra-cli will properly work.
Thanks,

Will dig into it later on to see if it's a bug.

Hi Aaron,
I'm using PropertyFileSnitch, an my cassandra-topology.propertis
looks like this:

10.11.1.108=DC1:RAC1

Hi Tyler,
No, it was just a typo in the email, I changed names of DC in the
email after copy/paste from output of the tools.
It is quite easy to reproduce (assuming you have a correct
configuration for NetworkTopologyStrategy, with vNodes(default,
256)):
1. launch cqlsh and create the keyspace
create keyspace foo with replication=
{'class':'NetworkTopologyStrategy','DC1':3};
2. exit cqlsh, run
nodetool describering foo
you'll see something like this:
TokenRange(start_token:2318224911779291128,
end_token:2351629206880900296, endpoints:[], rpc_endpoints:[],
endpoint_details:[])
TokenRange(start_token:-8291638263612363845,
end_token:-8224756763869823639, endpoints:[], rpc_endpoints:[],
endpoint_details:[])
3. start cqlsh,
drop keyspace foo;
4. Exit cqlsh, start cassandra-cli
create keyspace foo with placement_strategy =
'NetworkTopologyStrategy' AND strategy_options={DC1};
if you run nodetool describering foo you'll see:
TokenRange(start_token:2318224911779291128,
end_token:2351629206880900296, endpoints:[10.11.1.200,

endpoint_details:[EndpointDetails(host:10.11.1.200,

Gabriel,
It looks like you used "DC1" for the datacenter name in your
replication strategy options, while the actual datacenter name
was "DC-1" (based on the nodetool status output). Perhaps that
was causing the problem?

I do not think that it has anything to do with Astyanax, but
after I have recreated the keyspace with cassandra-cli,
everything is working fine.
Also, I have mention below that not even "nodetool describering
foo", did not showed correct information for the tokens,
encoding_details, if the keyspace was created with cqlsh.
Thanks,

Hi,
I have spent half of the day today trying to make a new
Cassandra cluster to work. I have setup a single data center
cluster, using NetworkTopologyStrategy, DC1:3.
I'm using latest version of Astyanax client to connect. After
many hours of debug, I found out that the problem may be in
cqlsh utility.
So, after the cluster was up and running:
[me@cassandra-node1 cassandra]$ nodetool status
Datacenter: DC-1

I went to create the keyspace:
1. First I have tried using cqlsh:
create keyspace foo with replication=
{'class':'NetworkTopologyStrategy','DC1':3};
after this, I have checked that the keyspace was properly
created by running
cqlsh> select * from system.schema_keyspaces;
keyspace_name | durable_writes |
strategy_class |
strategy_options
---------------+----------------+------------------------------------------------------+----------------------------
system_auth | True |
org.apache.cassandra.locator.SimpleStrategy |
{"replication_factor":"1"}
foo | True |
org.apache.cassandra.locator.NetworkTopologyStrategy |
{"dc1":"3"}
system | True |
org.apache.cassandra.locator.LocalStrategy
| {}
system_traces | True |
org.apache.cassandra.locator.SimpleStrategy |
{"replication_factor":"1"}
but if I run nodetool describering foo, it will not show
anything into endpoint, or endpoint_details fields.
In this situation, Astyanax client will throw exception with
NoAvailableHostsException. I have used following configuration:
withAstyanaxConfiguration(new AstyanaxConfigurationImpl()
.setDiscoveryType(NodeDiscoveryType.RING_DESCRIBE)
.setConnectionPoolType(ConnectionPoolType.TOKEN_AWARE)
First option did not worked at all.
2. I've dropped the keyspace crated with cqlsh and re-created
with cassandra-cli. This time, the nodetool describering foo,
shows information into endpoint and endpoint_details columns,
and also the Astyanax client works properly.
Hope it will avoid others to avoid spending time to figure out
how to go around this issue.

Gabi

tried out on a single node, but the cassandra-cli way showed no
endpoint details either
