tillrohrmann opened a new pull request #8096: [FLINK-12075][yarn] Set RestOptions.BIND_PORT only to 0 if not specified
URL: https://github.com/apache/flink/pull/8096
 
 
   ## What is the purpose of the change
   
   This PR changes the YarnEntrypointUtils#loadConfiguration so that it only
   sets RestOptions.BIND_PORT to 0 if it has not been specified. This allows to
   explicitly set a port range for Yarn applications which are running behind a
   firewall, for example.
   
   Moreover, this PR updates the flink-conf.yaml to contain the new rest options and comments
   out the `rest.port` per default so that it will be set to `0` in the Yarn case.
   
   ## Verifying this change
   
   * Added `YarnEntrypointUtilsTest`
