For example, if only a partial body is sent some fields may be null. I
couldn't quickly find a way to allow either all fields or non to be null.
> 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
> Assignee: Esteban Serrano
> Priority: Minor
> Labels: pull-request-available
>
> 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.
