Example 81 with PlainActionFuture

use of org.elasticsearch.action.support.PlainActionFuture in project crate by crate.

the class IndexShardTestCase method recoverUnstartedReplica.

/**
 * Recovers a replica from the give primary, allow the user to supply a custom recovery target. A typical usage of a custom recovery
 * target is to assert things in the various stages of recovery.
 *
 * Note: this method keeps the shard in {@link IndexShardState#POST_RECOVERY} and doesn't start it.
 *
 * @param replica                the recovery target shard
 * @param primary                the recovery source shard
 * @param targetSupplier         supplies an instance of {@link RecoveryTarget}
 * @param markAsRecovering       set to {@code false} if the replica is marked as recovering
