[FAQ] DDL job error count exceed the limit, cancelling it now

[问题澄清]

[WARN] [ddl_worker.go:578] ["[ddl] DDL job error count exceed the limit, cancelling it now"] [worker="worker 4, tp add index"] [jobID=48] [errorCountLimit=512]

[原因分析]

add index 的时候遇到错误,且重试报错超出了默认 512 次,系统自动取消此 add index 任务

[解决方案]

是否有报错:[tikv:9005]Region is unavailable ,如果有参考官网处理办法:Region is unavailable
