Siddharth Seth updated MAPREDUCE-4006:
--------------------------------------
Attachment: MR4006.txt
Trivial patch. Was appending the entire buffer to the output instead of the
amount read.
> 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
> Affects Versions: 0.23.2

> 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.
