> Samza stores the metadata of the job into a log-compacted kafka topic called
> coordinator stream.
> Due to some operational issue, we converted serialized null value into bytes
> and stored them as values for some keys in the coordinator stream. These keys
> will not be log-compacted by kafka, since they're not actually null messages.
> As a part of JIRA, we propose to ignore these configurations with
> serialized-null values and hold keys only with non-null values from
> coordinator-stream in ApplicationMaster.
