启动过程中遇到错误Cassandra 3.11.2

启动Cassandra作为org.apache.Cassandra.exceptions.ConfigurationException时，我遇到一个新错误：无效值？？选项“推测性重试”的百分位数

我正在Windows10Pro上使用ApacheCassandra3.11.2。如果有任何可能的解决办法，请告诉我

您在表创建语句中以与所需格式不匹配的方式定义了“重试”

可接受的格式示例（如果是数字，则必须介于0.0和100.0之间）：

或

检查您在架构中为表配置的内容。

感谢Valerie的更新。但我还没有创建任何表或模式。这是在新PC上新安装的Apache Cassandra，只是尝试启动Cassandra。您对Cassandra使用了什么安装方法？它是从Apache-Cassandra-3.11.2-bin.tar文件夹中提取的tarball。我通过命令提示符运行cassandra.bat，从“C:\Program Files\apache-cassandra-3.11.2\bin”路径启动cassandra，我总是在不同的机器上运行，但从未遇到此类错误。我在另一台机器上测试了相同的设置，它运行正常，但无法在我正在尝试的机器上解决此错误。

AND speculative_retry = '99.0PERCENTILE';

AND speculative_retry = 'NONE';
