Enis Soztutar commented on HADOOP-1494:
---------------------------------------
Also i cannot find the logs by {{TaskTracker$Child}}.
We pass
{code}
-Dhadoop.log.dir=/data/hadoop/logs
-Dhadoop.root.logger=INFO,TLA
-Dhadoop.tasklog.taskid=task_0008_r_000016_0
-Dhadoop.tasklog.noKeepSplits=4
-Dhadoop.tasklog.totalLogFileSize=102400
-Dhadoop.tasklog.purgeLogSplits=true
-Dhadoop.tasklog.logsRetainHours=12
{code}
to the child jvm but we do not specify the logging file name, so the logs at {{
TaskTracker$Child}} gets lost. I'm not an expert on logging, so correct me if
I'm wrong.
> TaskRunner.java unconditionally sets child vm hadoop.root.logger to INFO,TLA

> Key: HADOOP-1494
> URL: https://issues.apache.org/jira/browse/HADOOP-1494
> Project: Hadoop
> Issue Type: Bug
> Affects Versions: 0.13.0
> Reporter: Michael Bieniosek
> Priority: Minor
>
> When TaskRunner.java spins up a task in a child vm, it sets
> -Dhadoop.root.logger=INFO,TLA. This seems wrong. Maybe it would be better
> as System.getProperty("hadoop.root.logger")?
