Example 96 with Response

use of org.opensearch.client.Response in project OpenSearch by opensearch-project.

the class DanglingIndicesRestIT method testDanglingIndicesCanBeDeleted.

/**
 * Check that dangling indices can be deleted. Since this requires that
 * we add an entry to the index graveyard, the graveyard size must be
 * greater than 1. To test deletes, we set the index graveyard size to
 * 1, then create two indices and delete them both while one node in
 * the cluster is stopped. The deletion of the second pushes the deletion
 * of the first out of the graveyard. When the stopped node is resumed,
 * only the second index will be found into the graveyard and the the
 * other will be considered dangling, and can therefore be listed and
 * deleted through the API
