Restore zookeeper metadata

[Snehalata Nagaje <sn...@harbingergroup.com>]

Hi ,

We are using central standalone zookeeper for kafka and HBase .

Due to some problem, we have installed new zookeeper on different machine, 
but since we do not have old metadata available in Zookeeper required for 
kafka.

We are not able to read previous topic messages.

How we can restore old data to restore all metadata?



Thanks,
Snehalata

There is no easy way to move zookeeper data other than stopping all kafka
servers and clients, moving the zookeeper data manually and restarting the
server and clients with the new zookeeper url.

Thanks,

Are you running Kafka 0.7 or 0.8?
