Java 无法通过Phantom连接到Cassandra（NoHostAvailableException）

我在尝试从Scala应用程序插入Cassandra时收到以下错误代码

Cassandra版本与：dsc-Cassandra-3.0.1捆绑在一起

[错误]（run-main-0）com.datastax.driver.core.exceptions.NoHostAvailableException:所有尝试查询的主机均失败（尝试：localhost/127.0.0.1:9042（com.datastax.driver.core.exceptions.InvalidQueryException:未配置的表架构_键空间），localhost/0:0:0:0:0:0:0:0:0:1:9042（com.datastax.driver.core.TransportException:[localhost/0:0:0:0:0:0:0:1:9042]无法连接） com.datastax.driver.core.exceptions.NoHostAvailableException:所有尝试查询的主机均失败（尝试：localhost/127.0.0.1:9042（com.datastax.driver.core.exceptions.InvalidQueryException:未配置的表架构_键空间），localhost/0:0:0:0:0:0:0:1:9042（com.datastax.driver.core.TransportException:[localhost/0:0:0:0:0:0:0:1:9042]无法连接）

我已经阅读了StackOverflow中的其他此类问题，但尚未找到解决我的问题的方法

此外，我没有注意到任何其他错误日志中存在以下情况：

我读的

localhost/127.0.0.1:9042

这难道不能归结为

127.0.0.1/127.0.0.1:9402

——这就解释了为什么它找不到正确的端口开口

现在沿着这条路走下去，试着弄清楚这是不是一件事

确保卡桑德拉在运行

我还使用以下输出运行了sudolsof-I-p | grep-I“listen”（仅拉出java输出）：

你对这个问题有什么想法吗

已发现，但不确定是否相关：

如果需要，这里是

build.sbt

organization := "org.dyne.danielsan"

scalaVersion := "2.11.7"

crossScalaVersions := Seq("2.10.4", "2.11.2")

此错误：

com.datastax.driver.core.exceptions.InvalidQueryException:unconfigured table schema_keyspaces

使我相信您使用的phantom版本没有使用datastax java driver 3.0+。由于您正在连接到一个3.0集群，因此需要一个了解架构表的3.0驱动程序（system_schema.*而不是system.schema*）。如果升级到phantom dsl 1.21.0，应该可以解决此问题
