Hmm...not sure - perhaps you could share you zookeeper data (there is a dump to clipboard option in the admin ui, cloud tab). Anything else interesting in the logs?
Some zookeeper layout changes were made, and I'm not sure an upgrade from beta/alpha was ever really tested with them (I didn't make the changes) - you might try dropping everything in zookeeper (not your Solr indexes, just ZooKeeper data) and restarting the cluster. Just a guess though. The error itself is as it says - a defensive measure - each SolrCore tracks whether it thinks it's the leader locally in RAM - the cluster state also says who the leader is - if there is not agreement, the core won't act as the leader because something must be off. - Mark On Wed, Oct 31, 2012 at 9:53 AM, balaji.gandhi <jilaba.hin...@gmail.com> wrote: > Hi, > > After upgrading from Solr 4.0.0-Beta to Solr 4.0.0 we are getting this error > from ALL the leader nodes:- > > Oct 31, 2012 6:44:03 AM > org.apache.solr.update.processor.DistributedUpdateProcessor > doDefensiveChecks > SEVERE: ClusterState says we are the leader, but locally we don't think so > > Is there a configuration/schema change we are missing?
