We recently had a deployment where we had a ton of errors when calling Solr and the collections API. We saw nodes going into recovery mode and generally things were hosed. Restarting solr didn't help, but restarting zookeeper did. In our environment Zookeeper and Solr are on google cloud servers, only the admins have access to the file systems, is there a Zookeeper or Solrj API call that will return the status of the Zookeepers? How would we know if the zookeeper had lost its quorum?
Ideally this would be a call through the zkclient java interface. -- This message and any attachment are confidential and may be privileged or otherwise protected from disclosure.
