Summary: Decouple job parsing logic from SLSRunner
Key: YARN-10547
URL: https://issues.apache.org/jira/browse/YARN-10547
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Szilard Nemeth
Assignee: Szilard Nemeth
SLSRunner has too many responsibilities.
One of them is to parse the job details from the SLS input formats and launch

- Synth
- Rumen
Their job parsing method are:
- SLS trace:
