> I am getting cancelled key exception in zookeeper (version 3.4.5). Please see the log below. When this error is thrown, the connected solr shard is going down by giving the error "Failed to index metadata in Solr,StackTrace=SolrError: HTTP status 503.Reason: {"responseHeader":{"status":503,"QTime":204},"error":{"msg":"ClusterState says we are the leader, but locally we don't think so","code":503" and ultimately the current activity is going down. Could you please give a solution for this ?
