> Change ExecutionConfig#getGlobalJobParameters to return an instance of GlobalJobParameters
instead of null if no custom globalJobParameters are set yet

> Key: FLINK-9787
> URL: https://issues.apache.org/jira/browse/FLINK-9787
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Florian Schmidt
> Assignee: Ji Liu
> Priority: Minor
> Labels: pull-request-available
> Fix For: 2.0.0

>
> Currently when accessing ExecutionConfig#getGlobalJobParameters this will return `null`
if no globalJobParameters are set. This can easily lead to NullPointerExceptions when used
with getGlobalJobParameters.toMap()
> An easy improvement for this would be to just return a new instance of GlobalJobParameters
if none is set with the empty map as the parameters
> This would be a breaking change since we expose this via RuntimeContext#getExecutionConfig
