---------------------------------------
Summary: Allow setting yarn.nodemanager.delete.debug-delay-sec on
a per-job basis
Key: MAPREDUCE-4284
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4284
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Reporter: Ahmed Radwan
Assignee: Ahmed Radwan
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.
