Hi,
I have a streaming application that takes data from a kafka topic and uses
mapwithstate.
After couple of hours of smooth running of the application I see a problem
that seems to have stalled my application.
The batch seems to have been stuck after the following error popped up.
Has anyone seen this error or know what causes it?
