> Key: SAMZA-833
> URL: https://issues.apache.org/jira/browse/SAMZA-833
> Project: Samza
> Issue Type: Bug
> Reporter: Jake Maes
> Assignee: Tao Feng
> Fix For: 0.10.1

> As a result of SAMZA-465 and SAMZA-805, ProcessJobFactory now passes the full
> config to the ProcessJob and no longer forces the container count to 1. This
> causes the ProcessJob to actually read the container count config and if it
> is not 1, it produces some unexpected behavior.
> Specifically we've had reports of ProcessJobs dropping messages because the
> container count is > 1, so the grouper assigns partitions to more than 1
> container, but only one container actually runs.
> The goal of this ticket is to either force the container count to 1 for
> ProcessJob, or fix how multiple containers run with ProcessJob. But we should
> not allow the scenario where messages are dropped.
