我嘗試使用astyanax連接到本地cassandra，但不斷獲取PoolTimeoutException。我能夠使用cli或hector客戶端連接到cassandra。 任何想法我做錯了什麼？當通過Astyanax連接到Cassandra時出現PoolTimeoutException
謝謝。
我的代碼：
val context = new AstyanaxContext.Builder()
.forCluster("cluster")
.forKeyspace(keyspace)
.withAstyanaxConfiguration(
new AstyanaxConfigurationImpl()
.setDiscoveryType(NodeDiscoveryType.NONE)
)
.withConnectionPoolConfiguration(
new ConnectionPoolConfigurationImpl("ConnPool")
.setPort(9160)
.setMaxConnsPerHost(1)
.setMaxBlockedThreadsPerHost(1)
.setSeeds("127.0.0.1:9160")
.setConnectTimeout(10000)
)
.withConnectionPoolMonitor(new CountingConnectionPoolMonitor())
.buildKeyspace(ThriftFamilyFactory.getInstance())
context.start()
return context.getEntity()
例外：

「湯姆d」 好抓，謝謝！任何人在沒有maven的情況下將astyanax jar升級到v1.0.6時，不要忘記將libthrift升級到0.7.0 – 2012-08-09 13:38:32
