Shannon Carey commented on FLINK-5322:
--------------------------------------

Another important note: quoting strings doesn't work the way it should in YAML either.

> yarn.taskmanager.env:
>   MY_ENV: test
> {code}
> is not available in {{System.getenv("MY_ENV")}} from the plan execution (execution flow of main method) nor from within execution of a streaming operator.
> Interestingly, it does appear within the Flink JobManager Web UI under Job Manager -> Configuration.
> --------------------------
> The yarn section of the configuration page should be cleaned up a bit. The "yarn.containers.vcores" parameter is listed twice, the example for "yarn.application-master.env" is listed as a separate parameter and the "yarn.taskmanager.env" description indirectly references another parameter ("same as the above") which just isn't maintainable; instead it should be described similarly as the application-master entry.
