クラス RecoveryTarget

java.lang.Object

org.elasticsearch.common.component.AbstractComponent

org.elasticsearch.indices.recovery.RecoveryTarget

public class RecoveryTarget
extends AbstractComponent

The recovery target handles recoveries of peer shards of the shard+node to recover to.

Note, it can be safely assumed that there will only be a single recovery per shard (index+id) and not several of them (since we don't allocate several shard replicas to the same node).

メソッドの詳細

cancelRecoveriesForShard

public boolean cancelRecoveriesForShard(ShardId shardId,
                                        String reason,
                                        @Nullable
                                        com.google.common.base.Predicate<RecoveryStatus> shouldCancel)

cancel all ongoing recoveries for the given shard, if their status match a predicate

パラメータ:

reason - reason for cancellation

shardId - shardId for which to cancel recoveries

shouldCancel - a predicate to check if a recovery should be cancelled or not. Null means cancel without an extra check. note that the recovery state can change after this check, but before it is being cancelled via other already issued outstanding references.

戻り値:

true if a recovery was cancelled

startRecovery

public void startRecovery(IndexShard indexShard,
                          RecoveryState.Type recoveryType,
                          DiscoveryNode sourceNode,
                          RecoveryTarget.RecoveryListener listener)

retryRecovery

protected void retryRecovery(RecoveryStatus recoveryStatus,
                             String reason,
                             TimeValue retryAfter,
                             StartRecoveryRequest currentRequest)
