为什么flink 1.13.1, metrics指标中表名称为 Unnamed

Hi！

我执行如下sql任务时，打开度量报告，其中我的输出表度量指标中，表名显示为Unnamed，这是否为一个bug？

指标信息如下：

node103.taskmanager.container_1627469681067_0030_01_000002.e621b91ec4a34ababeb6b0e2c4d6f22b.Source: HiveSource-qc_test_t_student_score -> Calc(select=[id, CAST(_UTF-16LE'Bob':VARCHAR(2147483647) CHARACTER SET "UTF-16LE") AS name, class_id, class_name, score, _UTF-16LE'9bdb0e98cc5b4800ae3b56575c442225':VARCHAR(2147483647) CHARACTER SET "UTF-16LE" AS rule_id, _UTF-16LE'测试33333':VARCHAR(2147483647) CHARACTER SET "UTF-16LE" AS task_batch_id], where=[(name = _UTF-16LE'Bob':VARCHAR(2147483647) CHARACTER SET "UTF-16LE")]) -> Map -> Sink: Unnamed.0.Shuffle.Netty.Input.Buffers.inputFloatingBuffersUsage

任务sql如下：

CREATE CATALOG qc_hive_catalog WITH ( 'type' = 'hive', 'default-database' = 'qc_test' );

USE CATALOG qc_hive_catalog;

CREATE TABLE

IF

NOT EXISTS QC_RESULT_T_STUDENT_SCORE ( id STRING, NAME STRING, class_id STRING, class_name STRING, score INTEGER, rule_id STRING, task_batch_id STRING ) WITH ( 'is_generic' = 'false', 'connector' = 'hive' );

INSERT INTO QC_RESULT_T_STUDENT_SCORE SELECT

id,

NAME,

class_id,

class_name,

score,

cast( '9bdb0e98cc5b4800ae3b56575c442225' AS STRING ) AS rule_id,

cast( '测试33333' AS STRING ) AS task_batch_id 

FROM

t_student_score 

WHERE

t_student_score.NAME = 'Bob';*来自志愿者整理的flink邮件归档
