java - Apache Cassandra 3.10 IllegalArgumentException - Murmur3Partitioner 的 token 无效

Question

我正在使用的 token 值:

initial_token: 85070591730234615865843651857942052864

当我尝试启动 Cassandra 时，导致以下 Java 异常:

Exception (java.lang.IllegalArgumentException) encountered during startup: Invalid token for Murmur3Partitioner. Got 85070591730234615865843651857942052864 but expected a long value (unsigned 8 bytes integer).

Cassandra 在我的第一个节点上正常启动，initial_token: 0

我做错了什么？

非常感谢任何帮助!

我的主要问题是你为什么要设置它？

该 token (85070591730234615865843651857942052864)可能用于随机分区器，而不是杂音分区器。可以检查集群中的其他节点，但可能在 cassandra.yaml 中设置:

partitioner: org.apache.cassandra.dht.RandomPartitioner

Murmur3 分区器是更好的主意，但不确定您从哪里获得该 token 或为什么您希望它起作用。如果您只是添加节点，最好让它自己分配 token 。只是不要设置它。

# initial_token:
