版本更新时出现 ClickHouse 未知编解码器系列错误

Question

我一直在使用 ReplicatedMergeTree 创建一个包含表的三节点 ClickHouse 集群。我最近将它的一个节点从版本 18.14.2 更新为 19.3.7。但是，升级后，由于数据没有同步，我无法与升级后的节点建立连接。

ClickHouse 错误日志如下。

升级到 19.4.3.11 修复了这个错误。但是，现在不断出现以下错误，仍然无法与服务器建立连接。

(StorageReplicatedMergeTree): DB::StorageReplicatedMergeTree::queueTask()::: Poco::Exception。代码：1000，e.code() = 0，e.displayText() = Null 指针：_pInstance in file "/home/centos/clickhouse-rpm/rpmbuild/BUILD/ClickHouse-19.4.3.11-stable/contrib/poco/ Util/include/Poco/Util/Application.h”，第 457 行

发现上面是ClickHouse v19.4.3.11的另一个bug - https://github.com/yandex/ClickHouse/issues/5005

我遇到了同样的异常，需要在失败的节点上执行下面的查询（见github: DB::Exception: Unknown codec family code : 4）：
