vinoyang updated FLINK-12362:
-----------------------------
Description: The {{-n}} config option for Flink on YARN has been deprecated
and removed from documentation. However, there are still some legacy code
exists in the codebase. We need to clean up them. (was: 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
