集群配置：
4台16Core 64G内存机器，其中1台FE（硬盘500G SSD），3台BE（硬盘1T SSD）（一台混部FE Observer，混部FE单独500G SSD磁盘）

建表语句如下：
CREATE TABLE IF NOT EXISTS test_table_2
(
dateline BIGINT COMMENT '服务器时间，毫秒时间戳'
,dt date COMMENT '分区字段，天分区，yyyyMMdd'
,ht int COMMENT '分区字段，小时分区，格式HH'
)
DUPLICATE KEY(dateline,dt,ht)
COMMENT ''
PARTITION BY RANGE(dt, ht)
(
partition p20210401 VALUES [("2021-04-01","0"),("2021-04-01","24")),
partition p20210402 VALUES [("2021-04-02","0"),("2021-04-02","24")),
partition p20210403 VALUES [("2021-04-03","0"),("2021-04-03","24")),
partition p20210404 VALUES [("2021-04-04","0"),("2021-04-04","24")),
partition p20210405 VALUES [("2021-04-05","0"),("2021-04-05","24")),
partition p20210406 VALUES [("2021-04-06","0"),("2021-04-06","24")),
partition p20210407 VALUES [("2021-04-07","0"),("2021-04-07","24")),
partition p20210408 VALUES [("2021-04-08","0"),("2021-04-08","24")),
partition p20210409 VALUES [("2021-04-09","0"),("2021-04-09","24")),
partition p20210410 VALUES [("2021-04-10","0"),("2021-04-10","24")),
partition p20210411 VALUES [("2021-04-11","0"),("2021-04-11","24"))
)
DISTRIBUTED BY HASH(dateline) BUCKETS 16
;

插入语句：
insert into dy_dwd.dwd_dy_log_dot_hi_2(dateline,dt,ht) values(1618408080,'2021-04-01',5),(1618408081,'2021-04-01',6),......;
values中数据达到100条甚至更多

结果报错：
当values中数据达到100或者1000条甚至更多时，走mysql jdbc协议会出现如下错误
ERROR 5025 (HY000): errCode = 2, detailMessage = already stopped, skip waiting for close. cancelled/!eos: : 1/0

测试中发现每秒insert into的values个数据达到20之后就会出现上述错误，既然兼容MySQL协议，明显insert into导入数据的方式性能太低
