In our PROD SOLR cluster(7.6 and ZK:3.4.9) when Zookeeper leader fails Zookeeper enter an infinite leader election loop which makes SOLR instable. Solr Fails to index(as Expected with error "Remote error message: Cannot talk to ZooKeeper - Updates are disabled") and CPU spikes up.
This is a know ZK bug https://issues.apache.org/jira/browse/ZOOKEEPER-2164. below are my question: 1. Solr behaving Wonky when ZK quorom is affected is expected but is there a work around? 2. The ZK bug is fixed in 3.5.6 is solr7.6 compatible with ZK 3.5.6? 3. Anyone have an opinion around "fast leader election" vs "original UDP-based" of ZK. Will cahnge election algorithm version from 3->0 solve the issue? -- Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
