Hoss Man created SOLR-11824:
-------------------------------
Summary: distributed json.facet "type:range" can return buckets
out of order when mincount>0
Key: SOLR-11824
URL: https://issues.apache.org/jira/browse/SOLR-11824
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Facet Module
Reporter: Hoss Man
Discovered this while working on SOLR-3218, but it's a general problem with how
the code is designed (and the existing code even has a TODO in FacetRangeMerger
refering to the problem) ... this is essentially the same bug FacetComponent's
{{facet.range}} had that was fixed in SOLR-6154: When he coordinator "combines"
the response from each shard, the buckets can get out of order depending on
which buckets were excluded by the first shard to respond.
Depending on how many shards you have, it's fairly trivial to reproduce using
{{bin/solr -e cloud}} and the {{exampledocs/*.xml}} files...
