Hello all,
Finally, we found RCA for this *null *mystery
As christine shared, in below code, hostname is being prepended:
*private static String generateRid(SolrQueryRequest req) { String
hostName = req.getCoreContainer().getHostName(); return hostName + "-" +
ridCounter.getAndIncrement(); }*
In above code, hostname is being passed from *solr.in.sh
<http://solr.in.sh>* file
by default SOLR_HOST variable will be commented, we just have to overwrite
it
*SOLR_HOST="solrNode1a"*
*Thanks & Regards,*
*Uday Kumar*
