> We've seen a strong need for validating running samza jobs programmatically. Consider the following scenarios:
> 1) running samza as a service (as in SAMZA-849), which requires automated job validation when upgrading the framework for large number of jobs;
> 2) production monitoring, automated validation can run periodically and trigger alerts;
> 3) integration testing, which can use validation tool to check the job status.
> So a tool is needed to provide the checkout of job health. Minimally it will check:
> - job submission
> - app running
> - container count
> It should also be able to extend and validate the job metrics through metrics system, such as JMX. The user will be able to validate against important metrics such as process_count or message_behind_high_watermark.
