Hi, When I need to restart a Solrcloud cluster, I always do this: - log in into host nb1, stop solr - log in into host nb2, stop solr -... - log in into host nbX, stop solr - verify all hosts did stop - in host nb1, start solr - in host nb12, start solr -...
I always wondered, if this was not really needed, and I could just call 'restart' in every node, in a quick loop, and forget about it. Does anyone know if this is the case? My doubt is in regards to changing some config, and then doing the above (just restart nodes in a loop). For example, what if I change a config G used in collection C, and I restart just one of the nodes (N1), leaving the rest alone. If all the nodes contain a shard for C, what happens, N1 is using the new config and the rest are not? how is this handled? thanks xavier
