-----------------------------------
Summary: Inconsistent REST Parameter Name: `programArg` vs `programArgs`
Key: FLINK-14864
URL:
https://issues.apache.org/jira/browse/FLINK-14864 Project: Flink
Issue Type: Bug
Components: Runtime / REST
Affects Versions: 1.8.1
Environment: Running 1.8.1 on an AWS EMR cluster. Making a POST request with NodeJS (request library).
Reporter: Kelly Smith
The documentation specifies that you should provide a parameter called `programArg`.
*Repro*
Send JSON as a POST body to */jars/:jarid/run* with `programArg` as a parameter
*Expected*
Successfully starts the job passing in the values from `programArg`
*Actual*
**Returns error:
```
{"errors":["Request did not match expected format JarRunRequestBody."]}
```
Digging into the source code, it appears that _JarRunRequestBody_ expects the field to be plural: `programArgs`
[
https://github.com/apache/flink/blob/master/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/handlers/JarRequestBody.java#L44]
Changing the name of the parameter to `programArgs` results in the job being successfully submitted with no error.
