Noble Paul commented on SOLR-5756: ---------------------------------- bq.Do you think it would be safe to do this manually on a running cluster? It is never fully safe , There are intermediate state changes which you may lose bq. Suppose I wanted to try to write a patch for this issue to help solve it for everyone, is that a reasonable thing to attempt for someone with a lot of ZK knowledge but pretty new to Solr? bq. Is it too "soon" to do that? It is not too soon. 5.0 is out for a while A lot of ZK knowledge is not required to do this. You need to know how overseer updates state and how states are updated by {{ZkStateReader.createClusterStateWatchersAndUpdate}} in each node bq.Can you opine on the specifics of having an API to move the state out vs. a forced migration? I shall do a follow up comment of what are the steps involved in actually doing this > A utility API to move collections from internal to external > ----------------------------------------------------------- > > Key: SOLR-5756 > URL: https://issues.apache.org/jira/browse/SOLR-5756 > Project: Solr > Issue Type: Bug > Reporter: Noble Paul > Assignee: Noble Paul > > SOLR-5473 allows creation of collection with state stored outside of > clusterstate.json.
