-------------------------------------

             Summary: NPE using TermVectorComponent in combinition with ExactStatsCache -
Solr6
                 Key: SOLR-9114
                 URL: https://issues.apache.org/jira/browse/SOLR-9114
             Project: Solr
          Issue Type: Bug
    Affects Versions: 5.3
            Reporter: Andreas Daffner
            Assignee: Varun Thacker
             Fix For: 5.5, 6.0


Hello,

I am getting a NPE when using the TermVectorComponent in combinition with ExactStatsCache.
I am using SOLR 5.3.0 with 4 shards in total.

I set up my solrconfig.xml as described in these 2 links:
TermVectorComponent:
https://cwiki.apache.org/confluence/display/solr/The+Term+Vector+Component

ExactStatsCache:
https://cwiki.apache.org/confluence/display/solr/Distributed+Requests#Configuring+statsCache+implementation


My snippets from solrconfig.xml:
{code}
...
  <!--
    Stats Cache
    https://cwiki.apache.org/confluence/display/solr/Distributed+Requests#Configuring+statsCache+implementation
  -->
  <statsCache class="org.apache.solr.search.stats.ExactStatsCache"/>
  <!-- 
    Term Vector Component
    https://cwiki.apache.org/confluence/display/solr/The+Term+Vector+Component
    -->
  <searchComponent name="tvComponent" class="org.apache.solr.handler.component.TermVectorComponent"/>
  <requestHandler name="/tvrh" class="org.apache.solr.handler.component.SearchHandler">
    <lst name="defaults">
      <bool name="tv">true</bool>
    </lst>
    <arr name="last-components">
      <str>tvComponent</str>
    </arr>
  </requestHandler>
...
{code}


Unfortunately a request to SOLR like "http://host/solr/corename/tvrh?q=site_url_id:74" ends
up with this NPE:
{code}
4329458 ERROR (qtp59559151-17) [c:SingleDomainSite_11 s:shard1 r:core_node1 x:SingleDomainSite_11_shard1_replica1]

{code}

According to https://issues.apache.org/jira/browse/SOLR-7756 this Bug should be fixed with
SOLR 5.3.0, but obviously this NPE is still present.
Can you please help me here?
