[jira] [Commented] (FLINK-14250) Introduce separate "bin/flink runpy" and remove python support from "bin/flink run"

    [ https://issues.apache.org/jira/browse/FLINK-14250?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16939427#comment-16939427 ] 

Aljoscha Krettek commented on FLINK-14250:
------------------------------------------

This would be breaking for existing users that use "bin/flink run" for Python programs.

 

cc [~sunjincheng121], [~dianfu] (because of Python), [~Tison] (because of the ongoing executor work), what do you think about this?

> Currently, "bin/flink run" supports both Java and Python programs and there is quite some complexity in command line parsing and validation and the code is spread across different classes.
> I think if we had a separate "bin/flink runpy" then we could simplify the parsing quite a bit and the usage help of each command would only show those options that are relevant for the given use case.
