             Summary: 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


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 it fails.

I don't know why this condition is needed and removing it seems to fix the issue.
