回复：kafka Broker Znode TTL

[逐风者的祝福 <18...@qq.com>]

I think /broker/ids/ is registered as a temporary znode when the broker is down and znode will be removed .

Do Kafka Broker has configuration to specify TTL for kafka broker znodes
such  /broker/ids/

This is useful in case zookeeper cluster goes down and kafka broker
re-registers , in that case it fails to start as Zookeeper already has the
same broker id registered.

Hi,

This issue happens when your zookeeper cluster is down , in that case the
znode is not removed.

We are running both zookeeper and kafka at same machine , hence if the
machine goes down causing <= 50% node in zookeeper cluster, there is no way
currently to clear the  /broker/ids/ nodes.

Also i am not sure if same /broker/ids/ gets deleted as soon as kafka is
killed.

Thanks
Harish
