Hi all,

I'm using zooKeeper as a message queue, creating each task as a
persistent_sequential node under a folder (another node
created in persistent mode). It works well. However, once a reboot happened
on the server, the nodes will be lost.

Is  there a setting in zooKeeper so that the nodes won't be erased?

Thank you.

Yuhan

Are you using /tmp to store your datadir?

ah, you are right! that's why it has been erased. Thanks Patrick. :)

NP. You mentioned reboot, it's a pretty common misconfig. :-)
