推荐答案

您无法使用 thrift API 拍摄快照，但您可以使用 JMX 拍摄快照，这就是 nodetool 命令的工作原理.查看node工具源码这里，特别看handleSnapshot 方法.

You can't take a snapshot using the thrift API, but you can take a snapshot using JMX, which is how the nodetool command works. Look at the node tool source here, in particular look at the handleSnapshot method.
