Guessing from the message, java.lang.RuntimeException: [solrconfig.xml] indexDefaults/mergePolicy: missing mandatory attribute 'class'
somewhere in your solr configs you have something like: <mergePolicy> <int name="maxMergeAtOnce">10</int> <int name="segmentsPerTier">10</int> </mergePolicy> rather than <mergePolicy class="org.apache.lucene.index.TieredMergePolicy"> <int name="maxMergeAtOnce">10</int> <int name="segmentsPerTier">10</int> </mergePolicy> although I suppose this could be a misleading error message if, say, your classpath is confused or some such...
