Bug Report

Please answer these questions before submitting your issue. Thanks!

1. Minimal reproduce step (Required)

deploy cluster Enable TLS between TiDB Components

drop table if exists t;
create table t(a char(10), b varchar(255), c text(30), d tinytext, e longtext, f mediumtext) charset utf8mb4 collate utf8mb4_unicode_ci;
insert into t values('AAAAAbbbbb', 'AAAAAbbbbb', 'AAAAAbbbbb', 'AAAAAbbbbb', 'AAAAAbbbbb', 'AAAAAbbbbb');
create index idx_a on t (a(5));
create index idx_c on t (c(5));
create index idx_f on t (f(5));
alter table t add index idx_b(b(5));

2. What did you expect to see? (Required)

All ddl execute success

3. What did you see instead (Required)

add index may failed with error 8214, 'Cancelled DDL job' without any cancel SQL

[15:13:18]TiDB root:test> alter table t add index idx_b(b(5));
(8214, 'Cancelled DDL job')

you may need run many times to reproduce this.
