中止kafka重新分配分区行动

Question

我正在使用kafka 0.8.2并且我的一个kafka服务器已经死亡(无法恢复磁盘上的数据).复制为1的主题与死服务器上的一个分区有关.我认为重新分配会将该分区的元数据移动到新服务器而不需要数据,但重新分配仍然存在in progress.

我跑了:

$ /opt/kafka/kafka/bin/kafka-reassign-partitions.sh --zookeeper myzookeeper.my.com --reassignment-json-file new_assignment.json --verify
Status of partition reassignment:
Reassignment of partition [topicX,1] is still in progress

这将永远不会成功,因为死服务器永远不会回来.

在新服务器的日志中,我看到:

[2015-05-28 06:25:15,401] INFO Completed load of log topicX-1 with log end offset 0 (kafka.log.Log)

有没有办法强制它完成或中止重新分配行动？

您可以通过使用zookeeper shell删除zookeeper集群上的“ / admin / reassign_partitions” zk节点来中止分配，并将分配给无效代理的分区移动到新节点。
