錯誤：開始使用CassandraDaemon

Question

我試圖從Java開始卡桑德拉守護和我使用的代碼

Java代碼如下卡桑德拉數據庫：

 CassandraDaemon cassandraDaemon; 
     System.setProperty("cassandra.config", "file:/Users/mselv2/dse/dse-4.5.0/resources/cassandra/conf/cassandra.yaml"); 
     System.setProperty("log4j.configuration", "file:/Users/mselv2/dse/dse-4.5.0/resources/cassandra/conf/log4j-server.properties"); 
     System.setProperty("storage-config", "/Users/mselv2/dse/dse-4.5.0/resources/cassandra/conf/"); 
     System.setProperty("cassandra-foreground", "true"); 
     cassandraDaemon = new CassandraDaemon(); 
     cassandraDaemon.init(null); 
     cassandraThread.setDaemon(true); 
     cassandraThread.start(); 

例外：

Can't construct a java object for tag:yaml.org,2002:org.apache.cassandra.config.Config; exception=Cannot create property=batchlog_replay_throttle_in_kb for JavaBean=org.apache.cassandra.config.Config@1a42752a; Unable to find property 'batchlog_replay_throttle_in_kb' on class: org.apache.cassandra.config.Config

開發環境：

我使用的數據STAX卡桑德拉4.5.0版並使用啓動數據庫apaache卡桑德拉驅動程序。

請爲我的問題建議解決方案？

Answer 1

這是一個版本的問題。 batchlog_replay_throttle_in_kb在Cassandra 1.2中添加，這意味着您正在使用的JAR爲< = 1.1。檢查你的類路徑，並確保你只有你想要的版本的JAR。
