      • Remove the entry: 
        <requestHandler name="/replication" class="solr.ReplicationHandler" startup="lazy" />
    • For Cloudera Manager 5.x:
      • Login to the Navigator Metadata Server host and edit these files: 
        /usr/share/cmf/cloudera-navigator-server/search-schema/solr/2900/nav_elements/conf/solrconfig.xml
/usr/share/cmf/cloudera-navigator-server/search-schema/solr/2900/nav_relations/conf/solrconfig.xml
      • Remove the entry:
