> According to the [CLI documentation|https://ci.apache.org/projects/flink/flink-docs-stable/ops/cli.html#job-submission-examples] one can use the CLI with the following {{--target}} values: "remote", "local", "kubernetes-session", "yarn-per-job", "yarn-session", "yarn-application" and "kubernetes-application". However, when running the following commands:
> {{bin/flink run -t yarn-session -p 1 examples/streaming/WindowJoin.jar}} I get the following exception:
> {code}

> Obviously, the CLI is not intended to be started with these targets. I would suggest to improve the documentation stating which targets are valid and to improve the error messages when starting the CLI with a not supported target.
