---------------------------------------
Summary: NPE in FacetComponent countFacets()
Key: SOLR-11672
URL: https://issues.apache.org/jira/browse/SOLR-11672
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: search
Affects Versions: 6.1.1
Reporter: Andreas Schaefer
I have a SOLR installation with two shards and this Facet Query configuration:
<lst name="invariants">
<str name="facet.query">{!key="$0 - $50"}price_d:[* TO 50]</str>
....
</lst>
When I run a query and the first shard returns a facet count less than the
minimum count then it will remove that Facet Query from the list
FacetInfo.queryFacets map in the method: removeQueryFacetsUnderLimits(). When
the Facet Component is handled for the second shard the get() on
FacetInfo.queryFacets will return null (entry was removed) and the subsequent
call to qf.count() is throwing an NPE.
This code will fix the NPE but in my opinion the removal of the Query Facets
should be moved to finishStage() method in order to make sure that
countFacets() works w/o an NPE.
This issue was previously reported under 2803 as far as I understand it.
I am working on the 6.1.0-SNAPSHOT code base but looking at the latest code
this still seems to be an issue.
