【Flink】did not react to cancelling signal for 30 seconds Task did not exit gracefully within
1.背景
standalone模式下,任务运行一段时间taskmanager挂掉,报错如下:
Task ‘Source: Custom Source -> Map -> Map -> to: Row -> Map -> Sink: Unnamed (1/3)’ did not react to cancelling signal for 30 seconds Task did not exit gracefully within 180 + seconds.
修改配置文件flink-conf.yaml,添加配置task.cancellation.timeout: 0
这个配置的含义是,超时（以毫秒为单位），在此之后任务取消超时并导致致命的TaskManager错误。 值为0将禁用watch dog
