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,
Gabi

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.
Br,
Gabi
