無法獲得卡桑德拉的基本上班的applcation

這是我目前的錯誤：無法獲得卡桑德拉的基本上班的applcation

com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /127.0.0.1 (com.datastax.driver.core.TransportException: [/127.0.0.1] Unexpected exception triggered (java.lang.NoClassDefFoundError: Could not initialize class com.datastax.driver.core.Codec)))

我覺得我每進口假象提供IM我的pom.xml的，我需要（以及許多我不要試圖解決這個問題）。

我只是不明白爲什麼這不起作用？

這裏是我的完整性pom.xml：

有人可以提供我一些理解我爲什麼會得到這個例外？我有一個cassandra客戶端在本地運行。（版本1.2.11）。

這不是你的pom文件的問題。您的客戶端（DataStax Java驅動程序）無法訪問您的cassandra數據庫。這可能是由於幾個原因：

檢查您正在使用的節點的地址。
檢查還端口，卡桑德拉本地二進制協議的默認端口是9042

看來你cassandara服務器不聽你的要求。嘗試的telnet 127.0.0.1 9160

，如果你收到此的telnet：無法連接到遠程主機：拒絕連接的JDBC庫使用DataStax驅動程序，它更成熟，無bug

<dependency> 
<groupId>org.apache-extras.cassandra-jdbc</groupId> 
<artifactId>cassandra-jdbc</artifactId> 
<version>1.2.5</version> 
</dependency>

並重新啓動您的卡桑達拉

得到了太類似的問題：我的春天的應用程序失敗，並且我能夠通過設置配置文件cassandra.yaml中的rpc_port和native_transport_port來匹配用於連接的eaxct IP地址Ť o cassandra（即Cluster.builder（）。addContactPoints（... IP地址在這裏...）），但它是cqlsh不再開始，因爲主機沒有監聽...直到我意識到監聽器（RPC或本地傳輸）是要麼在127.0.0.1上進行監聽，要麼在主機的真正IP 10.0.0.5上進行監聽，這在這個實現中會有很大的不同！所以我解決了它通過調整cqlsh腳本也使用10.0.0.5並獲得解析爲127.0.0.1而不是10.0.0.5的本地主機名稱的rif ...這不符合最初的IP網絡原則以擁有最終應用程序做出這樣的改變。

我在一臺虛擬機上安裝了Cassandra服務器，我無法遠程訪問它。我得到異常：

com.datastax.driver.core.exceptions.NoHostAvailableException: 
All host(s) tried for query failed (tried: /192.168.1.76:9042 (com.datastax.driver.core.TransportException: [/192.168.1.76:9042] Cannot connect))

首先，我確認我無法通過Telnet訪問端口9042。

我解決了修改cassandra的問題。在卡桑德拉服務器YAML配置文件，用

rpc_address = 0.0.0.0 
broadcast_rpc_address = 1.2.3.4

這是因爲

rpc_address（或RPC_INTERFACE）用於客戶端連接， listen_address屬性是節點間通信。
