sstableloader. The error: could not achieve replication factor 2 (found 1 replicas only), check your keyspace replication settings

Question

我尝试将 sstableloader 实用程序用于 BulkLoad。 SStables 是通过使用像 https://github.com/yukim/cassandra-bulkload-example/blob/master/src/main/java/bulkload/BulkLoad.java.

这样的脚本创建的

当我在 node5 [10.0.2.2] 上启动 sstableload 时，出现以下错误：

./sstableloader data/keyspace1/ -d localhost
WARN  14:56:55 Error while computing token map for datacenter dc2: could not achieve replication factor 2 (found 1 replicas only), check your keyspace replication settings.
WARN  14:56:55 Error while computing token map for datacenter dc1: could not achieve replication factor 3 (found 0 replicas only), check your keyspace replication settings.

键空间信息：

cqlsh> DESCRIBE keyspace1;
CREATE KEYSPACE keyspace1 WITH replication = {'class': 'NetworkTopologyStrategy', 'dc1': '3', 'dc2': '2'}  AND durable_writes = true;

节点信息：

我尝试从 dc1 的节点 1（种子）开始，但我也得到了结果：

Answer 1

sstableloader 会有点启动 C*（不是在客户端模式），这需要节点的 cassandra.yaml 等并被赋予适当的种子节点。您是偶然运行在其中一个 dc2 节点上这样做的吗？如果节点没有在 localhost 接口上监听，它可能无法加入环以知道流向何处，并且 non-client 模式可能会扰乱副本计算。尝试提供 -d 10.0.1.1,10.0.1.2,10.0.2.1,10.0.2.2 作为您的种子

Answer 2

我的错误：

节点必须在 0.0.0.0 上监听 9042。更改 cassandra.yaml： rpc_address: localhost 到 rpc_address:
需要使用：./sstableloader data/keyspace1/tablename -d IPADDRESS

Answer 3

另请注意：当您在 CQLSH 中定义复制因子并指定数据中心时......

CREATE KEYSPACE keyspace1 WITH replication = {'class': 'NetworkTopologyStrategy', 'dc1': '3', 'dc2': '2'}  AND durable_writes = true;

其 大小写 敏感并且必须与您在卡桑德拉-rackdc.properties 文件

dc=dc1
rack=rack1

将这些混淆，您将收到相同的错误消息

sstableloader. The error: could not achieve replication factor 2 (found 1 replicas only), check your keyspace replication settings
