-------------------------------------
Summary: Provide way to preserve
Key: YARN-324
URL: https://issues.apache.org/jira/browse/YARN-324
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager, resourcemanager
Affects Versions: 2.0.3-alpha
Reporter: Lohit Vijayarenu
There should be a way to preserve container directories (along with
filecache/appcache) for offline debugging. As of today, if container completes
(either success or failure) it would get cleaned up. In case of failure it
becomes very hard to debug to find out what the case of failure is. Having
ability to preserve container directories will enable one to log into the
machine and debug further for failures.
