Ludovic Boutros updated SOLR-8117:
----------------------------------
Description:
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.
