> When log aggregation is enabled, going to the job history server UI for the AM container
log can show the log contents combined together.  Examples I've seen are portions of the syslog
contents appended to either the stderr or stdout contents.  The log corruption does not occur
when using the mapred job -logs command, so this appears to be something specific to the history
server web UI.
