Hi, using SOLR 5.2 after restarting the cluster, I get below exceptions org.apache.solr.cloud.ZkController; Timed out waiting to see all nodes published as DOWN in our cluster state.
followed by : org.apache.solr.common.SolrException; org.apache.solr.common.SolrException: No registered leader was found after waiting for 4000ms , collection: So looked into ZK tree, and saw a load of entries in /overseer/queue , so went off and cleaned up (removed all entries), restarted the cluster and now being able to index again. What might be the cause to this? Regards
