history server container log web UI sometimes combines stderr/stdout/syslog
contents together
---------------------------------------------------------------------------------------------
Key: MAPREDUCE-4006
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4006
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobhistoryserver, mrv2
Reporter: Jason Lowe
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.
