----------------------------------
Hi [~till.rohrmann] What's your opinion?
> Recover container number config option for Flink on yarn job cluster mode in
> the doc
> ------------------------------------------------------------------------------------

> Key: FLINK-12362
> URL: https://issues.apache.org/jira/browse/FLINK-12362
> Project: Flink
> Issue Type: Bug
> Components: Deployment / YARN
> Reporter: vinoyang
> Assignee: vinoyang
> Priority: Major
>
> Recently, the {{-n}} config option has been removed from the document, the
> commit is here:
> [https://github.com/apache/flink/commit/60507b8baf5fba999b7c2c45c150914f38f5ce38#diff-8ae07fac4c1f4137fc1ef062aef70115L100]
> I can understand that maybe this option is useless for Flink session. But for
> job cluster mode, remove this option would confuse the users:
> * the {{-n}} has been deprecated and replaced with {{-p}}?
> * {{-p}} means the job level parallelism, but if users want to set a single
> operator's parallelism? how to calculate the number of containers
> * the {{-n}} option still exists in {{FlinkYarnSessionCli}}
> * we have customized the source code which broken the rule: one container
> one slot, so the {{-n}} is still useful
>
