Ok, I figured the steps in case someone needs a reference. It required both zkcli and RELOAD to update the changes.
1. Use zkcli to load the changes. I ran it from the node which used the bootstrapping. sh zkcli.sh -cmd upconfig -zkhost zoohost1:2181 -confname myconf -solrhome /mnt/opt/solrhome/ -confdir /mnt/opt/solrhome/solr/collection1/conf/ 2. Use the same node to run the RELOAD http://54.151.xx.xxx:8983/solr/admin/cores?action=RELOAD&core=collection1 -- View this message in context: http://lucene.472066.n3.nabble.com/Unable-to-update-config-file-using-zkcli-or-RELOAD-tp4197376p4197393.html Sent from the Solr - User mailing list archive at Nabble.com.
