Hi community,

I have a question about flink on yarn ha , if active resourcemanager changed, what is the flink task staus. Is flink task running normally? Should I must restart my flink task to run？

Thanks to your reply.

Normally, Yarn RM switch should not cause any problem to the running Flink instance. Unless the RM switch takes too long and Flink happens to request new containers during that time, it might lead to resource allocation timeout.
