[jira] [Commented] (SOLR-14486) Autoscaling simulation framework
should stop using /clusterstate.json
[ https://issues.apache.org/jira/browse/SOLR-14486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17107653#comment-17107653 ]
Ilan Ginzburg commented on SOLR-14486:
--------------------------------------
Thanks [~ab] for creating this. I will keep the sim changes in SOLR-12823 to minimal (compile, but not necessarily have tests passing). If by then you have fixed this one then perfect, otherwise I'll get back to you to discuss options before I submit a PR there.
Were you thinking of replacing the clusterstate.json version by some usage of the ZooKeeper transaction id (zxid), or do you see an implementation where individual state.json version numbers can be used?

> In theory the simulation framework doesn't actually use this file, but {{SimClusterStateProvider}} relies on its versioning to keep its internal data structures in sync. This should be changed to use individual DocCollection / state.json znodeVersion instead.
