- tidb 和 lightning 版本是多少？
- 麻烦上传配置文件信息和导入命令
版本都是4.0.0
配置文件：# 转换数据的并发数，默认为逻辑 CPU 数量，不需要配置。
混合部署的情况下可以配置为逻辑 CPU 的 75% 大小。
region-concurrency =
日志
level = “info”
file = “tidb-lightning.log”
[tikv-importer]
tikv-importer 的监听地址，需改成 tikv-importer 服务器的实际地址。
addr = “10.77.80.223:8287”
backend = “tidb”
on-duplicate = “replace” # 或者 “error”、“ignore”
[mydumper]
Mydumper 源数据目录。
data-source-dir = “/opt”
[tidb]
目标集群的信息。tidb-server 的监听地址，填一个即可。
host = “10.77.80.223”
port = 4000
user = “root”
password = “”
表架构信息在从 TiDB 的“状态端口”获取。
status-port = 10080
pd-addr = “10.77.80.223:2379”
导入命令nohup ./tidb-lightning -config tidb-lightning.toml > nohup.out & 运行的脚本
这个报错看起来不是第一次导入的报错，可以先按照文档清空 checkpoint https://pingcap.com/docs-cn/stable/tidb-lightning/tidb-lightning-checkpoints/#断点续传的控制，然后再启动 lightning 试试。
还是同样的报错，
从上面的配置中，没有看到 checkpoint 相关的设置，这个可以发一下吗？另外询问下，要导入数据的规模大概是多少？
可以贴一下你运行的清楚 checkpoint 命令吗？ 以及 checkpoint 相关配置
这个问题解决了没有啊？小白在学习，也是在这一步报同样的错误，就一张几十行数据的表，也是报这样的错误。
这个问题后来怎么处理的，也遇到了
