问题描述
Astyanax 1.56.37连接到在Debian上运行的Cassandra 1.2.6:
当快速连续执行多个插入操作时，Cassandra群集仅包含一个位于10.10.1.141的节点，在看似随机的点上，我将在控制台中看到以下内容:
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
每次我尝试连接到此键空间后，每次尝试都会失败，并显示相同的消息.
Every attempt to connect to this keyspace after I get this fails with the same message.
这是我的配置:
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();
在随后的context.start()
推荐答案
我也遇到了同样的问题，即我的Cassandra和应用程序(Cassandra客户端)在不同的机器上运行.
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
当我检查Cassandra环状态时，我发现Cassandra的运行地址为127.0.0.1，而不是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

在conf/cassandra.yaml中，我为listen_address指定了主机名而不是IP地址. cassandra将主机名更改为localhost(127.0.0.1)，而不是实际IP(10.10.1.141).将listen_address更改为实际IP后，客户端成功建立连接.
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.
监听地址:10.10.1.141
