------------------------------------
Summary: Handling Error propagation between ZkJobCoordinator &
DebounceTimer
Key: SAMZA-1150
URL: https://issues.apache.org/jira/browse/SAMZA-1150
Project: Samza
Issue Type: Bug
Reporter: Navina Ramesh
Right now, I don't think we handle errors from any of the callback properly. As
far as I can tell, most of the errors should cause the processor to stop and
propagate the error to the user. But we need to carefully evaluate the various
error scenarios.
Through this JIRA, we need to answer the following:
1. How to handle errors/exceptions thrown in the callbacks that are executed
with the debounce timer?
2. Debounce timer has a category of tasks to run. What happens when one task
fails? Do we cancel the other pending tasks, if any ? Does the ordering of the
tasks matter at all?
