Version 6 has very sensitive/advanced/complex curator and zookeeper integration, because some classes are changed to "fix" the original OSGi problems in old version of curator. Upstream curator/zookeeper versions have (AFAIK) OSGi integration simply inherited from older contributions and sometimes it may cause problems in later versions - mostly related to Guava integration. > > I've configured a Camel Cluster Service based on the ZooKeeper > implementation, exposed a service in a bundle, and then I reference > this service in the bundle that provides routes using "master". > Which Camel version, Which Zookeeper version? > > But I've an exception that seems to be related to an internal > dependance of the ZooKeeper service : Caused by: > java.lang.ClassNotFoundException: > org.apache.curator.shaded.com.google.common.cache.CacheBuilder not > found by curator-framework > Which Curator version are you using? I've quickly checked versions between 2.6.0 and 5.1.0, but all these simply import-package com.google.common.cache - so they expect the package to come from Guava instead of being shaded/private-packaged.. > > I don't understand exactly what this "curator framework" does, but > something is probably missing in the camel-zookeeper feature. > Curator is to Zookeeper like Guava was supposed to be (integration/versioning problems aside) java.util collections.
