Hi Kevin,
The server increments a znode's cversion by one each time a change to
it's child list is made. Every znode has it's own cversion. It should
never decrease. If you delete a znode and create it a new then the
cversion is reset for that znode. The cversion also happens to be used

Hi,
I'd like to implement a feed loader with Hadoop and most likely HBase. I've
got around 1 million feeds, that should be loaded and checked for new entries.
However the feeds have different priorities based on their average update
frequency in the past and their relevance.
The feeds (url,
Hi Thomas,
There are a couple of projects inside Yahoo! that use ZooKeeper as an
event manager for feed processing.
I am little bit unclear on your example below. As I understand it-
1. There are 1 million feeds that will be stored in Hbase.

HI Kevin,
The cversion should be monotonically increasing for the the znode.
It would be a bug if its not. Can you please elaborate in which cases
you are seeing the cversion decreasing? If you can reproduce with

Hi Kevin,
Thanks for the info. Could you cut and paste the code you are using
that prints the view info?
That would help. We can then create a jira and follow up on that.
Also, a zookeeper client can never go
We did have a case where the user setup 3 servers, each was standalone.
:-) Doesn't look like that's the problem here though given you only
specify 1 server in the connect string (although as mahadev mentioned
