> Key: SOLR-13159
> URL: https://issues.apache.org/jira/browse/SOLR-13159
> Project: Solr
> Issue Type: Bug
> Components: AutoScaling
> Affects Versions: 8.0
> Reporter: Gus Heck
> Assignee: Andrzej Bialecki
> Priority: Major
> Attachments: SOLR-13159.patch, autoscaling.json, 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
