Subject Re: zooKeeper connectionloss on a folder
Date Tue, 01 May 2012 17:17:39 GMT
More than 100000 objects under a node... I restarted last night with an
empty folder,
and the new folder reaches the same state. It kept happening..

I'm using the curator library to add objects.
(com.netflix.curator.framework.recipes.queue.DistributedQueue)  But feeling
it is a
problem of ZooKeeper.

Thank you.

Yuhan
