【问题标题】：ERROR : Starting cassandra database using CassandraDaemon错误：使用 CassandraDaemon 启动 cassandra 数据库
【发布时间】：2014-07-17 13:42:18
【问题描述】：

我正在尝试从 java 启动 cassandra 守护程序，我正在使用以下代码

JAVA 代码：

        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：

开发环境：

我正在使用 data stax cassandra 4.5.0 版并使用 apaache cassandra 驱动程序来启动数据库。

请为我的问题提出解决方案？

谢谢，穆图·塞尔万 SR

标签： cassandra datastax

【解决方案1】：

这是版本控制问题。 batchlog_replay_throttle_in_kb 是在 Cassandra 1.2 中添加的，这意味着您使用的 JAR 适用于

【讨论】：

谢谢理查德，我已经设置了 $CASSANDRA_HOME=/Users/mselv2/dse/dse-4.5.0 是指最新版本的 cassandra ，在运行我的代码之前我是否应该设置其他任何东西，请指教!
CASSANDRA_HOME 没有帮助，因为您是从自己的代码运行它。你的类路径是什么？
export CLASSPATH=/Users/mselv2/dse/dse-4.5.0/lib ，我刚刚使用上述命令导出了 CLASSPATH 并运行了命令但仍然出现相同的错误，你想要吗我在 CLASSPATH 中设置了其他任何东西，请指教！我已经引用了网址：datastax.com/docs/1.0/references/cassandra 并运行了“cassandra.in.sh”，但仍然出现错误
使用 -cp 参数设置类路径要安全得多。您需要检查不同版本的 cassandra 的类路径。此外，该链接适用于 Cassandra 1.0，但您使用的 DSE 版本适用于 Cassandra 2.0。
感谢您的更新，我已经更新了 cassandra /Users/mselv2/dse/dse-4.5.0/lib 的 -cp dnd 我运行了 /Users/mselv2/dse 中的 shell 脚本/dse-4.5.0/bin/dse-env.sh 但我得到了同样的错误，你能帮忙设置一下运行我的代码所需的类路径变量吗？
