             Summary: Use a new abstract class for ContainerLauncher(s) that provide dagComplete() functionality
                 Key: TEZ-3729
                 URL: https://issues.apache.org/jira/browse/TEZ-3729
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Kuhu Shukla
            Assignee: Kuhu Shukla


This JIRA will address the following review comment from [~jlowe].

{code}
Does it make sense to create an abstract class in tez-common that derives from ContainerLauncher and has an abstract dagComplete method? Then we can have the existing launchers derive from that rather than ContainerLauncher directly and can RTTI check against that one class rather than maintain a specific list of container launchers.
{code}
