apache-kafka - KAFKA - 如何重新平衡可用经纪人的分区

Question

我们有 3 台 kafka 机器和 3 台 Zookeeper 的服务器

kafka1 - 1001 ( broker ID )
kafka2 - 1002 ( broker ID )
kafka3 - 1003 ( broker ID )

我们有问题即将重新平衡可用代理的分区，我们可以看到（向下）一些分区复制不足，isr 中只有两个代理。取而代之的是 3

在 ISR 中重新平衡 kafka 主题分区的最佳方法是什么

第二 - 我们可以看到领导者 1002 丢失了，解决方案是什么？

备注 - 我们有 23 个主题（下面的列表是部分的）

如何影响分区领导有两种选择。将配置选项auto.leader.rebalance.enable设置为true（这应该是默认设置）后，Kafka 将自动尝试将每个分区的领导权移动到您首选的代理。首选代理是副本列表中的第一个。它作为定期检查执行，因此可能不会立即发生。

或者 - 如果关闭自动重新平衡 - 您可以使用该bin/kafka-preferred-replica-election.sh工具手动重新分配副本。有关更多信息，请参阅Kafka 文档。

但是，在您的情况下，您的代理 1002 似乎是在重新启动后不久，或者可能需要更多时间来重新同步数据，因为代理 1002 还不是所有分区的 ISR。如果这是永久状态，并且您 100% 确定您的代理有足够的时间来同步所有分区等，那么 1002 可能还有其他一些问题。但是如果没有来自代理等的日志，这很难说。
