Thanks Jan We are using Solr 6.6.3 version. We didn't configure RunExecutableListener in solrconfig.xml, it seems configured in configoverlay.json as default. Even we don't want to configure RunExecutableListener.
Is it mandatory to use configoverlay.json or can we get rid of it? If yes can you share details. Attached the solrconfig.xml solrconfig.xml <http://lucene.472066.n3.nabble.com/file/t86258/solrconfig.xml> -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
