我正在尝试在我的集群上部署cassandra datastax enterprise 4.5.1，而且我总是得到java.lang.AssertionError，日志如下：

Note that the default partitioner starting with Cassandra 1.2 is Murmur3Partitioner, so you will need to edit that to match your old partitioner if upgrading.

任何人都知道这个或者可能给我任何信息吗？任何答案将不胜感激
答案 0 :(得分：0)
问题解决了，正如@RussS所说，这是因为分区器不匹配，我们应该在cassandra.yaml中使用 partitioner：org.apache.cassandra.dht.RandomPartitioner
