             Summary: Allow REST API for running a job to provide job configuration as body of POST request
                 Key: FLINK-9499
                 URL: https://issues.apache.org/jira/browse/FLINK-9499
             Project: Flink
          Issue Type: Improvement
          Components: REST
    Affects Versions: 1.3.2
            Reporter: Esteban Serrano


Based on [this|https://ci.apache.org/projects/flink/flink-docs-release-1.3/monitoring/rest_api.html#submitting-programs] documentation, the REST API provides a way to submit a request for running a Flink job. The POST request must include the job configuration information as query parameters using the documented parameter names ("program-args", "entry-class", "parallelism", etc.) 

Depending on the job parameters, the full URL for the POST request can reach a size that is over the maximum size (currently at 4096 bytes) of what is allowed by the configuration of Netty. To overcome this, it would be useful to allow users to provide the job configuration not only as query parameters but also as POST parameters. 

For the most part, it is the "program-args" parameter that can make the URL grow in size based on the needs of the developer and the job. All other attributes should be pretty constant.
