未能通過Phantom連接到Cassandra（NoHostAvailableException）

當通過來自Scala應用程序的Phantom嘗試插入卡桑德拉時，我得到以下錯誤代碼。未能通過Phantom連接到Cassandra（NoHostAvailableException）

卡桑德拉版本是捆綁：DSC-卡桑德拉 - 3.0.1

[error] (run-main-0) com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: localhost/127.0.0.1:9042 (com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces), 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] Cannot connect)) com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: localhost/127.0.0.1:9042 (com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces), 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] Cannot connect))

我已經通過StackOverflow的其他此類問題閱讀，但還沒有找到一個解決我的問題。

此外，我還沒有發現任何其他錯誤日誌下面的存在：在讀localhost/127.0.0.1:9042

我是正確，這是否歸結爲127.0.0.1/127.0.0.1:9402 - 這可以解釋爲什麼它找不到正確的端口開放。

現在走下這條路，試圖弄清楚這是不是一件事。

已確保Cassandra正在運行。

I also ran sudo lsof -i -P | grep -i "listen" with the following output (just pulling out the java ones):

java 4053 dan_mi_sun 85u IPv4 0xdbcce7039c377b9d 0t0 TCP localhost:7199 (LISTEN) 
java 4053 dan_mi_sun 86u IPv4 0xdbcce703986952cd 0t0 TCP localhost:53680 (LISTEN)

java 4053 dan_mi_sun 145u IPv4 0xdbcce7039c37846d 0t0 TCP localhost:9042 (LISTEN)

什麼的問題可能是有什麼想法？

有沒有發現這一點，但不知道這是否是相關的：

此錯誤：com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces使我相信您正在使用的幻影版本不使用datastax java-driver 3.0+。由於您連接到3.0羣集，因此您需要一個能夠理解架構表（system_schema。*而不是system.schema *）的3.0驅動程序。如果你升級到phantom-dsl 1.21.0，那應該解決這個問題。
