dolphinscheduler的僵尸任务清理

原因：海豚调度中有几百条僵尸任务， 界面怎么也删不掉，想从数据库中删除，开始查找从数据库删除的办法。

参考以下脚本，结合我库中僵尸任务的特征，用end_time is null删除了大半。
– 删除 任务实力中运行的任务
select * from t_ds_process_instance where end_time is null and command_type=9

实在找不到特征的，就按名字删除了。

– 删除 任务实力中运行的任务
select * from t_ds_process_instance where end_time is null and command_type=9 – state=6 end_time is null

#删除工作流实例
select * from t_ds_process_instance where DATE_FORMAT(start_time ,“%Y-%m-%d”) = ‘2021-06-23’;

delete from t_ds_process_instance where DATE_FORMAT(start_time ,“%Y-%m-%d”) = ‘2021-06-23’ and state = ‘1’;

#删除工作流
select * from t_ds_process_definition where DATE_FORMAT(create_time ,“%Y-%m-%d”) = ‘2021-06-23’;
