Shalin Shekhar Mangar commented on SOLR-13815: ---------------------------------------------- Probably too late for this comment but... bq. Still... I don't think zookeeper can update multiple znodes at the same time, so we might still have a very small window where we see something like inactive/construction/construction. I'm not sure what the behavior of the current code would be in that case. Actually inactive/construction/construction is impossible because the shard state is coming from the clusterstate which is a single znode updated atomically. So the states will either be active/construction/construction or active/recovery/recovery or inactive/active/active. No other state is possible. > Live split can lose data > ------------------------ > > Key: SOLR-13815 > URL: https://issues.apache.org/jira/browse/SOLR-13815 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level.
