Gus Heck commented on SOLR-13159:
---------------------------------
I should note that the autoscaling.json I'm attaching has been fiddled with
repeatedly (using the API) trying to find settings that would get the cluster
to balance out. It's not the state that was active when the cluster was
created. (that would have been whatever the distribution default is).
> Autoscaling not distributing collection evenly

> Key: SOLR-13159
> URL: https://issues.apache.org/jira/browse/SOLR-13159
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: AutoScaling
> Affects Versions: 8.0
> Reporter: Gus Heck
> Priority: Major
> Attachments: clstat.json
>
>
> I recently ran into a very strange behavior described in detail in the mail
> linked at the bottom of this description. In short:
> # Default settings didn't distribute nodes evenly on brand new 50 node
> cluster
> # Can't seem to write rules producing suggestions to distribute them evenly
> # Suggestions are made that then fail despite quiet cluster, no changes.
> Also of note was diagnostic output containing this seemingly impossible
> result with 2 cores counted and no replicas listed:
> {code:java}
> {
> "node": "solr-2.customer.redacted.com:8983_solr",
> "isLive": true,
> "cores": 2,
> "freedisk": 140.03918838500977,
> "totaldisk": 147.5209503173828,
> "replicas": {}
> },{code}
> I will attach anonymized cluster status output and autoscaling.json shortly
> This issue may be related to SOLR-13142
