In order for the code bellow to work:

► Make sure to update the variables ("solrUrl", "collectionName", ...) with your information.

final String[] solrUrl = { "http://localhost:8983/solr" }; final CloudSolrClient cloudSolrClient = new CloudSolrClient.Builder(Arrays.asList(solrUrl)).build(); final String aliasName = "alias1"; final String aliasedCollections = "collection1,collection2"; // create alias { final CollectionAdminRequest.CreateAlias adminRequest = CollectionAdminRequest.CreateAlias.createAlias(aliasName, aliasedCollections); CollectionAdminResponse adminResponse = adminRequest.process(cloudSolrClient); System.out.println(adminResponse); } cloudSolrClient.close();

final String[] solrUrl = { "http://localhost:8983/solr" }; final CloudSolrClient cloudSolrClient = new CloudSolrClient.Builder(Arrays.asList(solrUrl)).build(); final String aliasName = "alias1"; // delete alias { final CollectionAdminRequest.DeleteAlias adminRequest = CollectionAdminRequest.DeleteAlias.deleteAlias(aliasName); CollectionAdminResponse adminResponse = adminRequest.process(cloudSolrClient); System.out.println(adminResponse); } cloudSolrClient.close();
