actions in metastore on job restarts)
> Tie Container placement service and Container placement handler and validate
> placement requests

> Key: SAMZA-2402
> URL: https://issues.apache.org/jira/browse/SAMZA-2402
> Project: Samza
> Issue Type: New Feature
> Reporter: Sanil Jain
> Assignee: Sanil Jain
> Priority: Major
>
> On job restarts, there might be already pending container placement requests
> from the previous deployment. Since a new deploy can potentially change the
> job state (some containers might lose affinity), we should not allow pending
> control actions to be taken from the previous deployment
> Also even if the metastore is eventually consistent, duplicate actions
> delivered to the metastore should be only taken once
