Flink在第一个Sink失败的情况下 导致 在switch 有遇到过嘛？-云小二-阿里云

Flink在第一个Sink失败的情况下 导致 在switch source算子运行状态 从running变成 cancelling 失败
报错 是因为 ResultSet.close()方法阻塞住了， 然后超过 task.cancellation.timeout 设置的时间 taskmanager就宕机了 有大佬遇到过嘛？Source（Mysql ） -> filter -> Sink(Mysql)
-> filter -> SinkWARN org.apache.flink.runtime.taskmanager.Task [] – Task ‘DataSource (PFFF7AF61-7336-EF96-F823-31CE49B07791) (1/1)#0’ did not react to cancelling signal – interrupting; it is stuck for 30 seconds in method:

以下为热心网友提供的参考意见

这个问题可能是由于在第一个Sink失败后，Flink尝试关闭ResultSet时阻塞了。你可以尝试增加task.cancellation.timeout的值来解决这个问题
