------------------------------------
Summary: Let ParameterTool return a dedicated GlobalJobParameters
object
Key: FLINK-7947
URL: https://issues.apache.org/jira/browse/FLINK-7947
Project: Flink
Issue Type: Improvement
Components: Client
Affects Versions: 1.4.0
Reporter: Till Rohrmann
The {{ParameterTool}} directly implements the {{GlobalJobParameters}}
interface. Additionally it has grown over time to not only store the
configuration parameters but also to record which parameters have been
requested and what default value was set. This information is irrelevant on the
server side when setting a {{GlobalJobParameters}} object via
{{ExecutionConfig#setGlobalJobParameters}}.
Since we don't separate the {{ParameterTool}} logic and the actual data view,
users ran into problems when reusing the same {{ParameterTool}} to start
multiple jobs concurrently (see FLINK-7943). I think it would be a much clearer
separation of concerns if we would actually split the {{GlobalJobParameters}}
from the {{ParameterTool}}.
