             Summary: FieldCache insanity with field used as facet and group
                 Key: SOLR-4866
                 URL: https://issues.apache.org/jira/browse/SOLR-4866
             Project: Solr
          Issue Type: Bug
            Reporter: Sannier Elodie
            Priority: Minor


I am using the Lucene FieldCache with SolrCloud 4.2.1 and I have "insane" instances for a field used as facet and group field.

schema fieldType & filed declaration for my
merchantid field :
<fieldType name="int" class="solr.TrieIntField" precisionStep="0" sortMissingLast="true" omitNorms="true" positionIncrementGap="0"/>

<field name="merchantid" type="int" indexed="true" stored="true" required="true"/>

The mbean stats output shows the field cache insanity after executing queries like :
/select?q=*:*&facet=true&facet.field=merchantid
/select?q=*:*&group=true&group.field=merchantid

<int name="insanity_count">25</int>
<str name="insanity#0">VALUEMISMATCH: Multiple distinct value objects for SegmentCoreReader(owner=_1z1(4.2.1):C3916)+merchantid
