Log Context

Log “[{}][{}] recovery from [{}] failed” classname is RecoveryTarget.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 if (cause instanceof AlreadyClosedException) {
                    listener.onIgnoreRecovery(true; "source shard is closed (" + request.sourceNode() + ")");
                    return;
                }

                logger.warn("[{}][{}] recovery from [{}] failed"; e; request.shardId().index().name(); request.shardId().id(); request.sourceNode());
                listener.onRecoveryFailure(new RecoveryFailedException(request; e); true);
            } finally {
                shard.store().decRef();
            }
        } else {
