Description

I am trying to work with multi-threaded faceting on SolrCloud and in the process i was hit by some issues.

I am currently running the below upstream test on different SolrCloud configurations and i am getting a different result set per configuration.
https://github.com/apache/lucene-solr/blob/trunk/solr/core/src/test/org/apache/solr/request/TestFaceting.java#L654

Setup:

Indexed 50 docs into SolrCloud.

If the SolrCloud has only 1 shard, the facet field query has the below output (which matches with the expected upstream test output - # facet fields ~ 50).

$ curl  "http://localhost:8983/solr/collection1/select?facet=true&fl=id&indent=true&q=id%3A*&facet.limit=-1&facet.threads=1000&facet.field=f0_ws&facet.field=f0_ws&facet.field=f0_ws&facet.field=f0_ws&facet.field=f0_ws&facet.field=f1_ws&facet.field=f1_ws&facet.field=f1_ws&facet.field=f1_ws&facet.field=f1_ws&facet.field=f2_ws&facet.field=f2_ws&facet.field=f2_ws&facet.field=f2_ws&facet.field=f2_ws&facet.field=f3_ws&facet.field=f3_ws&facet.field=f3_ws&facet.field=f3_ws&facet.field=f3_ws&facet.field=f4_ws&facet.field=f4_ws&facet.field=f4_ws&facet.field=f4_ws&facet.field=f4_ws&facet.field=f5_ws&facet.field=f5_ws&facet.field=f5_ws&facet.field=f5_ws&facet.field=f5_ws&facet.field=f6_ws&facet.field=f6_ws&facet.field=f6_ws&facet.field=f6_ws&facet.field=f6_ws&facet.field=f7_ws&facet.field=f7_ws&facet.field=f7_ws&facet.field=f7_ws&facet.field=f7_ws&facet.field=f8_ws&facet.field=f8_ws&facet.field=f8_ws&facet.field=f8_ws&facet.field=f8_ws&facet.field=f9_ws&facet.field=f9_ws&facet.field=f9_ws&facet.field=f9_ws&facet.field=f9_ws&rows=1&wt=xml"

Now, if a create a new collection with 2 shards (>1 shard SolrCloud), the same above query results in a different output. (# facet fields ~ 10 ; Expected 50)

This behavior is quite strange as it is being dependent on the number of shards in SolrCloud. It would be great if someone can shed some light on this?
