也就是说NameNode端写缓存是单线程操作,但是Sync可能是批量操作,但是从客户端角度来看写请求都会保证数据安全落到JouranlNode后才会返回,所以整体上看NameNode具备强一致性保证,当然整个文件系统强一致保证由多个部分共同支撑,这里不再展开。
ha-sync-mode: manual: this is the default mode. A new queue mirror will not receive existing messages, it will only receive new messages. The new queue mirror will become an exact replica of the leader over time, once consumers have drained messages that only exist on the leader. If the...

当处于 Active 状态的 NameNode 调用 FSEditLog 类的 logSync 方法来提交 EditLog 的时候,会通过 JouranlSet 同时向本地磁盘目录和 JournalNode 集群上的共享存储目录写入 EditLog。写入 JournalNode 集群是通过并行调用每一个 JournalNode 的 QJournalProtocol RPC 接口的 journal 方法实现的,如果对大多数 JournalNode...

数据恢复后,ANN上会将本地处于in-process状态的日志更名为finalized状态的日志,形式如edits[start-txid][stop-txid]。 3.日志同步 这个步骤上面有介绍到关于日志从ANN同步到JN的过程,具体如下: 执行logSync过程,将ANN上的日志数据放到缓存队列中将缓存中数据同步到JN,JN有相应线程来处理logEdits请求JN收到数据后,先...
