Astyanax 1.56.37 connecting to Cassandra 1.2.6 running on Debian:
When performing a number of inserts in quick succession to a Cassandra cluster containing only one node located at 10.10.1.141, at seemingly random points, I will see the following in the console:
- AddHost: 127.0.0.1
- RemoveHost: 10.10.1.141
Every attempt to connect to this keyspace after I get this fails with the same message.
Here is my configuration:
AstyanaxContext<Keyspace> context = new AstyanaxContext.Builder()
.forCluster("Titan Cluster")
.forKeyspace(keyspaceName)
.withAstyanaxConfiguration(new AstyanaxConfigurationImpl()
.setConnectionPoolType(ConnectionPoolType.TOKEN_AWARE)
.setDiscoveryType(NodeDiscoveryType.RING_DESCRIBE)
.setTargetCassandraVersion("1.2")
)
.withConnectionPoolConfiguration(new ConnectionPoolConfigurationImpl("MyConnectionPool")
.setPort(9160)
.setMaxConnsPerHost(50)
.setSeeds("10.10.1.141:9160")
.setConnectTimeout(2000)
.setSocketTimeout(30000)
.setMaxTimeoutWhenExhausted(10000)
.setMaxTimeoutCount(3)
.setTimeoutWindow(10000)
.setLatencyAwareBadnessThreshold(10)
.setLatencyAwareUpdateInterval(1000)
.setLatencyAwareResetInterval(10000)
.setLatencyAwareWindowSize(100)
)
.withConnectionPoolMonitor(new CountingConnectionPoolMonitor())
.buildKeyspace(ThriftFamilyFactory.getInstance());
context.start();
The connection fails on subsequent attempts at context.start()
I too faced the same issue where I had my Cassandra and application (Cassandra client) running on different machines.
AddHost: 10.10.1.141
AddHost: 127.0.0.1
RemoveHost: 10.10.1.141
When I checked my Cassandra ring status, I noticed that the Cassandra was running with the address 127.0.0.1, instead of 10.10.1.141

In conf/cassandra.yaml, I had specified the hostname instead of IP address for listen_address. The cassandra resoved the hostname to localhost (127.0.0.1) instead of the actual IP (10.10.1.141).
After changing the listen_address to the actual IP, the client established connection successfully.
listen_address: 10.10.1.141
