问题是 also asked on the #cassandra channel在 ASF Slack所以我在这里重新发布以供后代使用。
根据堆栈跟踪，尝试访问 system.size_estimates 的快照子目录时似乎失败了。和 system.table_estimates .
尽管我没有足够的信息来确认这一点，但目录可能因停电(首先重新启动节点的原因)而损坏。
在任何情况下，解决方法是手动删除 size_estimates/ 的快照目录。和 table_estimates/在 data/system/* .这将允许 Cassandra 成功启动。干杯!
附言贾博超在 ASF Slack 上证实，该解决方法允许他们在节点上启动 C*。
