Description

The yarn.nodemanager.delete.debug-delay-sec property is helpful in debugging jobs (inspecting container logs/local dirs after the job finishes). Currently it is a nodemanager property and changing it requires restarting the nodemanager. In a production cluster this can be a real problem. It is better to have this property set on a per-job basis and not requiring the restart of nodemanagers.
