--------------------------------------
Summary: 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
Reporter: Florian Schmidt
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
