[Zookeeper-user] zookeeper vs. heartbeat messages

[Stefan G. <sg...@10...>]

Hi
I'm new to zookeeper and I work on a system that require classical  
master - slave communication similar to hadoop dfs or hbase.
Though in my case the master need to know much faster if a slave  
crashes than in other cases.
So I wonder if it would make sense instead of using classical  
heartbeat messages in can use zookeeper.
Basically the master need to know if a new slave becomes available and  
what kind of data it servers.

Is there any limitations where the amount of data stored within  
zookeeper becomes an issue?
Would you recommend to use zookeeper over heartbeat messages?

Thanks for any hints.
Stefan
