-------------------------------------
Hi!
There are various reasons causing heartbeat timeout, among which the most
frequent reason is heavy GC. Please check the GC log of your job and try to
increase the resources for each task manager. If you have other questions, feel
free to post them in the [user mailing
list|https://flink.apache.org/community.html#mailing-lists].
Closing this issue as this is not a bug.
