Patrick Hunt commented on ZOOKEEPER-107:
----------------------------------------
I've only been following this a bit, and I see bits/pieces in the comments but
not sure I follow it all -- some questions around the plan wrt manageability:
1) adding removing servers, server itself needs to be configured, any changes
needed to config on existing ensemble? I see Raghu has similar comment on this
2) JMX - what's the plan? what additional properties/actions will be supported?
3) 4letter words - same issues as jmx
4) debug-ability - ensure adequate logging (log4j) on ensemble
5) security - will an ensemble allow any server to connect to it? today we have
ensemble participants hardwired into the config of each of the servers right?
testing and b/w compat -- are we ensuring b/w compat btw this version and
previous versions? (I'm probably going to look at beefing up unit & systest
next, esp around b/w compat, so would be good to have a better idea where this
is headed). IMO this patch must include unit as well as systest before it is
committed.
documentation will be needed as well.
Perhaps a wiki "proposal" page should be created that will capture the "current
proposal" for easy review of this feature? This JIRA can capture ongoing
discussion, with agreed upon results capture in the wiki design/functional
document. I know it would help me alot.
