[jira] [Commented] (MAPREDUCE-4970) Child tasks (try to) create security audit log files

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4970?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13568338#comment-13568338 ] 

Sandy Ryza commented on MAPREDUCE-4970:
---------------------------------------

I propose creating a task-log4j.properties without the SecurityAuth logger, and passing that instead of the default to the task.  This is what MR2 does, with container-log4j.properties.

> After HADOOP-8552, MR child tasks will attempt to create security audit log files with their user names.  On an insecure cluster, this has no effect, but on a secure cluster, log4j will try to create log files for tasks with names like SecurityAuth-joeuser.log.
