Hello, I'm challenged with cluster recovery. Think about total failure: ZK state is lost, however instanceDirs survived since they are mounted via EBS. Let's say collection is read/only and/or it doesn't have replicas, just leaders. Is there a way to create a new empty collection and say, hey here's shard1 instance, shard2 instance is there etc?
Customer says that the old version of solr does it automatically: when empty zk is connected, collection's shards just appear there. Right now due to https://issues.apache.org/jira/browse/SOLR-12066 Cleanup deleted core when node start - if instances with data dirs connect to empty ZK it just wipes dirs away. Thanks -- Sincerely yours Mikhail Khludnev
