在使用flink cdc,配置任务运行,过了几天后,任务无故取消,超时,导致taskmanager挂掉,相关异常如下: 异常1: did not react to cancelling signal interrupting; it is stuck for 30 seconds in method:org.apache.flink.connector.idbc.internal.JdbcoutputFormat,flush (idbcoutoutFormat.iava:215) 异常2: 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.

处理该问题,需要在 flink-conf.yaml配置文件加上: 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。
