Examples with ClusterName org.elasticsearch.cluster.ClusterName used on opensource projects

Example 76 with ClusterName

use of org.elasticsearch.cluster.ClusterName in project elasticsearch by elastic.

the class IndicesServiceTests method testIndexAndTombstoneWithSameNameOnStartup.

/**
     * This test checks an edge case where, if a node had an index (lets call it A with UUID 1), then
     * deleted it (so a tombstone entry for A will exist in the cluster state), then created
     * a new index A with UUID 2, then shutdown, when the node comes back online, it will look at the
     * tombstones for deletions, and it should proceed with trying to delete A with UUID 1 and not
     * throw any errors that the index still exists in the cluster state.  This is a case of ensuring
     * that tombstones that have the same name as current valid indices don't cause confusion by
     * trying to delete an index that exists.
     * See https://github.com/elastic/elasticsearch/issues/18054
