我有一个失败的 scalatest 套件，我已将原因缩小到在测试之前运行并截断数据表的代码。如果我运行以下代码，我可以重新创建问题

session.execute(s"TRUNCATE ${dao.tableName};")
session.execute(s"TRUNCATE ${dao.tableName};")

抛出：

我正在使用 datastax 驱动程序 2.0.0-RC2，并且有一个由三个节点组成的集群。

关于这里出了什么问题的任何想法？

Turns out this was an issue with a node that had got into an inconsistent state due to running out of diskspace

这是因为一致性级别。您不能使用一致性级别 ALL 截断所有节点数据。您必须将一致性级别设置为一或二，然后它将在一段时间后截断来自一个节点的所有数据，该节点将截断来自其他节点的所有数据。
