Re: [ecf-dev] ZooKeeper configuration through ZooDiscovery

[Wim Jongman <wim.jongman@xxxxxxxxx>]

Hi,

Yes, multiple zookeepers on the same machine pointing to the same datadir could cause this. Override the datadir to a unique location.

zookeeper flags can be passed to the zoodiscovery through system properties e.g.

-Dzoodiscovery.dataDir=etc 

See the update wikipage for more information.

Regards,

Wim

Hi (Wim?),

a have this error with ZooKeeper, the same you noticed in September. What would be the best way to configure my ZooKeeper instanced in OSGi/ECF which is created by my container? Where to put/set zoo.cfg?

Thanks!

Martin

----------

IContainer container = ContainerFactory.getDefault().createContainer("ecf.discovery.zoodiscovery");
ID target = container.getConnectNamespace().createInstance(
       new String[] {"zoodiscovery.flavor.centralized=" + ip});
container.connect(target, null);
