             Summary: DistributedShell should initialize TimelineClient 
conditionally
                 Key: YARN-10209
                 URL: https://issues.apache.org/jira/browse/YARN-10209
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.6.0
            Reporter: Benjamin Teke


YarnConfiguration was changed along with the introduction of newer Timeline 
Service versions to include configuration about the used version. In Hadoop 
2.6.0 the distributed shell instantiates Timeline Client whether if it's 
enabled in the configuration or not. Running this distributed shell on newer 
Hadoop versions (where the new Timeline Service is available) causes an 
exception, because the bundled YarnConfiguration doesn't have the necessary 
version configuration property. Making the Timeline Client initialization 
conditional the distributed shell would run at least with disabled Timeline 
Service.
