我已经成功地建立了一个有7个节点的cassandra集群。但是，我无法让它用于基本查询。

CREATE TABLE lgrsettings (
  siteid bigint,
  channel int,
  name text,
  offset float,
  scalefactor float,
  units text,
  PRIMARY KEY (siteid, channel)
)

insert into lgrsettings (siteid,channel,name,offset,scalefactor,units) values (999,1,'Flow',0.0,1.0,'m');

然后在一个节点上：

select * from lgrsettings;

Request did not complete within rpc_timeout.

另一方面：

select * from lgrsettings;
Bad Request: unconfigured columnfamily lgrsettings

即使键空间和列族显示在所有节点上。
你知道我可以从哪里开始找吗？

有趣的结果。处理键空间创建和插入的节点显示：

其他节点在cfstats中没有，但是在descripe keyspace testdata中显示了它；在cql3客户端中。。。
