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.

> 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")?
