zooKeeper connectionloss on a folder
Yuhan Zhang 2012-05-01, 03:24
Hi all,

I'm using zooKeeper as a task queue; however, it appears that the folder
(zookeeper data node) that I used to store the tasks
(zooKeeper data nodes) are not accessible anymore - whenever I run an "ls"
through zkCli.sh, the app will quit with a connectionLoss.

The other folders are ok. and viewable using "ls".

Is the file corrupted? There are a lot of objects in the files. Is there a
limit for the number of object can be stored in a folder (node)?
Thank you.

Yuhan Zhang
