Description

Flink CLI treats job arguments provided in format "-<char>" as its own parameters, which results in errors in execution.

Example 1:
call: >bin/flink info myJarFile.jar -f flink -i <filepath> -m 1
error: Unrecognized option: -f

Example 2:
Job myJarFile.jar is uploaded to web submission client, flink parameter box is empty
program arguments box: -f flink -i <filepath> -m 1
error:
An unexpected error occurred:
Unrecognized option: -f
org.apache.flink.client.cli.CliArgsException: Unrecognized option: -f

Execution of
>bin/flink run myJarFile.jar -f flink -i <filepath> -m 1
works perfectly fine
