             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 the AMs and task containers.
As a first step, the job parser logic could be decoupled from this class.

There are 3 types of inputs: 
- SLS trace
- Synth
- Rumen

Their job parsing method are: 
- SLS trace: https://github.com/apache/hadoop/blob/005b854f6bad66defafae0abf95dabc6c36ca8b1/hadoop-tools/hadoop-sls/src/main/java/org/apache/hadoop/yarn/sls/SLSRunner.java#L479-L526
- Synth: https://github.com/apache/hadoop/blob/005b854f6bad66defafae0abf95dabc6c36ca8b1/hadoop-tools/hadoop-sls/src/main/java/org/apache/hadoop/yarn/sls/SLSRunner.java#L722-L790
- Rumen: https://github.com/apache/hadoop/blob/005b854f6bad66defafae0abf95dabc6c36ca8b1/hadoop-tools/hadoop-sls/src/main/java/org/apache/hadoop/yarn/sls/SLSRunner.java#L651-L716
