Subject [jira] [Created] (YARN-2533) Redirect stdout and stderr to a file for all applications/frameworks
Date Wed, 10 Sep 2014 22:44:34 GMT
Kannan Rajah created YARN-2533:
----------------------------------

             Summary: Redirect stdout and stderr to a file for all applications/frameworks
                 Key: YARN-2533
                 URL: https://issues.apache.org/jira/browse/YARN-2533
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: log-aggregation
    Affects Versions: 2.4.1
            Reporter: Kannan Rajah
            Priority: Minor


Today, we have the capability to redirect stdout and stderr of shell commands (launched tasks)
to a file and also apply a tail length. This logic exists in TaskLog, YARNRunner. But these
reside in map reduce specific packages. Every framework has to duplicate this logic. It would
be nice to abstract this at YARN level and apply to shell commands that are launched by any
framework.

ContainerLaunch.call method looks like a good candidate. Does anyone have suggestions or guidelines?
