Allen Wittenauer resolved MAPREDUCE-1776.
-----------------------------------------
Resolution: Incomplete
> Hadoop should provide a simplified way of fetching user-logs
> ------------------------------------------------------------
>
> Key: MAPREDUCE-1776
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1776
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Components: tasktracker
> Affects Versions: 0.20.1, 0.20.2
> Reporter: Alok Singh
>
> Hi,
> Currently , in both streaming and normal mode hadoop mapred program, user
> can't download the
> logs programatically.
> jobclient.output.filter=ALL, allows user to print output in the stdout/stderr
> We need to have the ability to fetch the user logs from the framework.
> in 0.18, under the hod , we used to store the logs in the hdfs.
> For 0.20, as long as the jobhistory resides user can view the logs but then
> it's gone.
> So in short , I am proposing that hadoop
> 1) provide the options to the JobClient (i.e jobconf var
> jobclient.output.logs.location), so that it will download the output in the
> hdfs location instead of printing to stdout.
> Thanks
