Take a condition {{cores>1}}.
This condition can be validated only in the end, because when you start
assigning replicas , cores=0 . In the end you will have to check if it is
indeed greater than 1

> Rule-based placement issue with 'cores' tag

> Key: SOLR-8117
> URL: https://issues.apache.org/jira/browse/SOLR-8117
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 5.3, 5.3.1
> Reporter: Ludovic Boutros
> Assignee: Noble Paul
> Attachments: SOLR-8117.patch
>
>
> The rule-based placement fails on an empty node (core count = 0) with
> condition 'cores:<1'.
> It also fails if current core number is equal to the core number in the
> condition - 1.
> During the placement strategy process, the core counts for a node are
> incremented when all the rules match.
> At the end of the code, an additional verification of all the conditions is
> done with incremented core count and therefore it fails.
> I don't know why this additional verification is needed and removing it seems
> to fix the issue.
