Varun Thacker created SOLR-12442:
------------------------------------
Summary: Improve error message when a policy is violated while
creating a collection
Key: SOLR-12442
URL: https://issues.apache.org/jira/browse/SOLR-12442
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Environment: On master when I have this policy setup
{code:java}
curl -X POST -H 'Content-type:application/json' --data-binary '{
"set-cluster-policy": [
{"cores": "<4","node": "#ANY"}
]
}' http://localhost:8983/solr/admin/autoscaling{code}
Now if I try to create a collection where the policy will get violated , I'll
get the following message in as a response
{code:java}

Which doesn't tell the user much about the error.
Here's what's available in the logs
