| Re: [smila-dev] Zookeeper fatal error and SMILA shutdown |
Hi Andreas, it’s the branch we created to implement Solr. So except some Solr specific bugfixes (which I’m going to merge back to trunk soon by the way) it’s the original trunk some time ago. I wondered about the NoClassDefFoundError too. First I thought some import is missing in Zookeeper extension jar, but since it’s coming as single bundle there’s nothing to import. As this is the only error in log I don’t think it’s some aftereffect. Thank you anyway! Best regards Peter From: smila-dev-bounces@xxxxxxxxxxx [mailto:smila-dev-bounces@xxxxxxxxxxx] On Behalf Of Andreas Weber Hi Peter, never saw something like that with zookeeper before. (NoClassDefFoundError ???) Are you doing something special in that branch? Is it possible that the main error happened before and this was a subsequent error? Best Regards, Andreas Von: smila-dev-bounces@xxxxxxxxxxx [mailto:smila-dev-bounces@xxxxxxxxxxx] Im Auftrag von Peter Wissel Hi folks, lately I was wondering why my SMILA instance doesn’t answer anymore. When I took a look in log file I found this exceptions followed by a graceful shutdown of the framework: 2012-10-21 00:57:27,873 WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181 ] server.NIOServerCnxn -
