> Apache DolphinScheduler-Parameter coverage
> ------------------------------------------
>
> Key: COMDEV-412
> URL: https://issues.apache.org/jira/browse/COMDEV-412
> Project: Community Development
> Issue Type: Improvement
> Components: GSoC/Mentoring ideas
> Reporter: Calvin Kirs
> Priority: Major
> Labels: DolphinScheduler, gsoc2021, mentor
>
> *Apache DolphinScheduler*
> Apache DolphinScheduler is a distributed and extensible workflow scheduler
> platform with powerful DAG visual interfaces, dedicated to solving complex
> job dependencies in the data pipeline and providing various types of jobs
> available out of the box.
> Page:https://dolphinscheduler.apache.org
> GitHub: https://github.com/apache/incubator-dolphinscheduler
> *Background:*
> Configuration parameter override
> At present, our parameter configuration is mainly based on configuration
> files: you can refer to PropertiesUtils,
> But usually important parameters will be injected through the form of Java
> runtime virtual machine parameters, so we need to support this way of
> parameter injection. At the same time, because different ways of parameter
> injection have different priorities, we need to achieve configuration
> coverage. There are two main situations at present, SystemProperties and
> LocalFile. The priority of SystemProperties should be the highest, followed
> by LocalFile (that is, our various configuration files, such as
> master.properties).
> issue:
> https://github.com/apache/incubator-dolphinscheduler/issues/5164
> for example:
> 1: Configure master.max.cpuload.avg=-1 in master.prperties
> 2: Java runtime virtual machine parameters -Dmaster.max.cpuload.avg=1
> 3:PropertiesUtils.get("master.max.cpuload.avg") = 1
> *Task*: realize configuration parameter coverage
