Subject [jira] [Commented] (CHUKWA-670) Use ZooKeeper for collector list and adaptor check list
Date Thu, 29 Nov 2012 22:10:58 GMT


Sourygna Luangsay commented on CHUKWA-670:

Still, I don't really understand what would be the benefit to have a centralized Zookeeper
configuration system instead of using Puppet or Chef.
Maybe, what you want to do is getting sure that the collector list is always "up-to-date"
(that is, if a collector node fails, it will be immediately removed from the list), so that
there would be no HTTP time-out from an agent trying to reach an unavailable collector. Is
that your idea?

Could you please detail the use-case that gives you the need to implement this ZK feature?

 This can be hard to manage for large scale system that needs to be updated more frequently.
 The proposal is to have a new configuration in chukwa agent configuration file to enable
ZooKeeper as the location to store check point file and collector list.
