Subject [jira] [Commented] (SOLR-6629) Watch /collections zk node on all nodes
Date Mon, 10 Aug 2015 18:27:46 GMT

    [ https://issues.apache.org/jira/browse/SOLR-6629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14680507#comment-14680507

Scott Blum commented on SOLR-6629:
----------------------------------

Now that SOLR-5756 is landed, can we flesh this ticket out some more?
Does this boil down to "watchChildren on /collections at all times, and actively manage the
lazy-loaded collection state list"?

> The main clusterstate.json is refreshed/used as a poor substitute for informing all nodes
about new or deleted collections even when the collection being created or deleted has state
format > 1. When we move away from state format 1 then we should do away with this workaround
and start watching the /collections zk node on all nodes.
