私はMacのドッカー内で最新バージョンのcassandraを実行しています。私はMacにcassandra開発センターをインストールしました。そして、私はdevcenterを使ってcassandraに接続することができ、簡単にテーブルを照会することができます。Astyanaxを使用してCassandraに接続できません

私はカサンドラのために必要なすべてのポートも開いていることがわかります。私はまた私のカサンドラ容器に、ログインし、私は
val configImpl = new AstyanaxConfigurationImpl()
configImpl.setDiscoveryType(NodeDiscoveryType.RING_DESCRIBE)
configImpl.setCqlVersion("3.4.2")
configImpl.setTargetCassandraVersion("3.7")
val poolConfig = new ConnectionPoolConfigurationImpl("MyConnectionPool")
poolConfig.setPort(9160)
poolConfig.setMaxConnsPerHost(1)
poolConfig.setSeeds("192.168.1.169")
val context = new AstyanaxContext.Builder()
.forCluster("localhost")
.forKeyspace("movielens_small")
.withAstyanaxConfiguration(configImpl)
.withConnectionPoolConfiguration(poolConfig)
.withConnectionPoolMonitor(new CountingConnectionPoolMonitor())
.buildKeyspace(ThriftFamilyFactory.getInstance())
context.start()
val keyspace = context.getClient()
val cf = new ColumnFamily[UUID, String]("cf", UUIDSerializer.get, StringSerializer.get())
val result = keyspace.prepareQuery(cf).withCql("select name from movies").execute()
val data = result.getResult.getRows()
for {
row <- data
col <- row.getColumns
} {
println(col)
}
context.shutdown()
以下のコードを実行したときしかし、私は取得するには、次のコマンド
[email protected]:/# nodetool -h 127.0.0.1 enablethrift
[email protected]:/# nodetool -h 127.0.0.1 statusthrift
running
を実行
