我们有一个包含两个节点的集群 . 当我执行create table命令时，该表实际上只在一个节点上创建：

CREATE TABLE prod.users_test（user_name varchar，password varchar，gender varchar，session_token varchar，state varchar，birth_year bigint，PRIMARY KEY（user_name））;

这在上次我们在集群上创建表时工作得很好 . 已经有一段时间但没有任何改变 . 群集工作正常，并且在旧表中的两个节点之间复制数据 .

如果我在两个节点上手动创建表并在一个节点上执行插入，则会将其复制到另一个节点 .

知道为什么它现在不能在两个节点上创建吗？

这是键空间描述：

CREATE KEYSPACE prod WITH replication = {
 'class': 'NetworkTopologyStrategy',
 'PRODDC1': '2' };

   CREATE TABLE users_test (
 user_name text,
 birth_year bigint,
 gender text,
 password text,
 session_token text,
 state text,
 PRIMARY KEY (user_name)
) WITH
 bloom_filter_fp_chance=0.010000 AND
 caching='KEYS_ONLY' AND
 comment='' AND
 dclocal_read_repair_chance=0.000000 AND
 gc_grace_seconds=864000 AND
 index_interval=128 AND
 read_repair_chance=0.100000 AND
 replicate_on_write='true' AND
 populate_io_cache_on_flush='false' AND
 default_time_to_live=0 AND
 speculative_retry='99.0PERCENTILE' AND
 memtable_flush_period_in_ms=0 AND
compaction={'class': 'SizeTieredCompactionStrategy'} AND
 compression={'sstable_compression': 'LZ4Compressor'};`
