Hi, If someone forgets to populate a bootstrap topic before starting a job, the job will hang indefinitely without processing any non-bootstrap messages, even if the bootstrap topic later populated. This is unexpected and hard for operations to debug.
I think Samza should either treat empty bootstrap topics as already caught up or as fatal errors. I created a JIRA here: https://issues.apache.org/jira/browse/SAMZA-502 Thanks, Roger
