问题:重建表过程中,先使用drop table xxx on cluster xxx ,各节点在clickhouse上table已物理删除,但是zk里面针对某个clickhouse节点的table meta信息未被删除(低概率事件),因zk里仍存在该表的meta信息,导致再次创建该表create table xxx on cluster, 该节点无法创建表(其他节点创建表成功),报错: Replica /clickhouse...
1 分布式 DDL 某数据节点的副本不执行 (1)问题:使用分布式 ddl 执行命令 create table on cluster xxxx 某个节点上没有创建 表,但是 client 返回正常,查看日志有如下报错。 <Error> xxx.xxx: Retrying createReplica(), because some other replicas were created at the same time (2)解决办法:重启该不执行...

7)Code: 253, Replica /clickhouse/tables/XXX/XXX/replicas/dba07 already exists 原因:建立副本表(ReplicatedMergeTree)的时候,如果数据库的引擎是Atomic,则在删除表之后马上重建会报这个错。删除的时候clickhouse是通过异步线程清除掉zookeeper上的数据的,立马新建的话可能异步线程还没开始执行,如果不想做其他操作的话...
Replica /clickhouse/tables/01-03/xxxxxx/xxx/replicas/xxx already exists. 解决办法:从其他数据副本 cp 该 table 的 metadata sql 过来。重启节点 6. ClickHouse 节点意外关闭 问题:模拟其中一个节点意外宕机,在大量 insert 数据的情况下,关闭某个节点。 现象:数据写入不受影响、数据查询不受影响、建表 DDL 执...

By doing this, there are no existing databases, it's as if it is brand new. The other 2 replicas are up and happy. The first step, as i can see it, is to get my schema correct. When i restore usingclickhouse-backupI get the above messages (REPLICA_IS_ALREADY_EXIST) because as ...

解决:可以将查询范围缩⼩,⽐如添加查询条件对查询结果取余,也可以清理或者添加物理机内存。5)DB::Exception: Table columns structure in ZooKeeper is different from local table structure (version 20.12.3.3 (official build))原因:Replicated(副本)表删表重建,但zk中表结构删除操作是异步的,默认为...
