Cassandra3.11.0
在ubuntu 16.04.4、jre-8中运行
我正在尝试创建一个具有uuid字段的表，如下所示：

CREATE TABLE IF NOT EXISTS policy (
  tenant_id         text,
  policy_id         uuid,
  name              text,
  enabled           boolean,
  creation_time     bigint,
  PRIMARY KEY (tenant_id, name)
);

执行此操作后，架构将“policy\u id”显示为“timeuuid”，而不是“uuid”。
看到了一个[类似的问题]：使用cassandraadminoperations.createtable在cassandra表中创建uuid类型字段
但这是否适用于cqlsh？
删除表/键空间并重试，但没有成功。
这是间歇性问题。
获取以下异常：

Exception while loading CQL script:

在cassandra日志中也可以看到：

策略\u id应具有数据类型“uuid”，但它具有数据类型“timeuuid”。
在cql语句中需要任何额外的关键字来创建表吗？
