Hi Srikanth, You are correct that in a NiFi cluster the intent would be to schedule GetSolr on the primary node only (on the scheduling tab) so that only one node in your cluster was extracting data.
GetSolr determines which SolrJ client to use based on the "Solr Type" property, so if you select "Cloud" it will use SolrCloudClient. It would send the query to one node based on the cluster state from ZooKeeper, and then that Solr node performs the distributed query. Did you have a specific use case where you wanted to query each shard individually? I think it would be straight forward to expose something on GetSolr that would set "distrib=false" on the query so that Solr would not execute a distributed query. You would then most likely create separate instances of GetSolr and configure them as Standard type pointing at the respective shards. Let us know if that is something you are interested in.
