------------------------------------
Sorry turns out -yD key=value actually works
> Expose YARN Dynamic configuration option flag for flink CLI run
> ---------------------------------------------------------------

> Key: FLINK-13559
> URL: https://issues.apache.org/jira/browse/FLINK-13559
> Project: Flink
> Issue Type: New Feature
> Components: Command Line Client
> Reporter: Gyula Fora
> Priority: Minor
>
> When running flink on yarn, the yarn-session component understand a dynamic
> option parameter which allows us to define/overwrite flink conf params from
> the deploy command.
> This is however not accessible when we use the flink run command to start a
> single job yarn cluster as the command line client fails on this unknown
> parameter.
> Simply adding this extra option to the flink run-options would let flink
> forward this parameter to the yarn session thus enabling this already
> existing feature.
> In addition I suggest we add the extra "conf" long option name for this
> parameter:
> flink run {{-m yarn-cluster}} --conf key=value ...
> or
> flink run {{-m yarn-cluster}} --Dkey=value ...
