Doug Cutting commented on MAPREDUCE-157:
----------------------------------------
Jothi, if you have an early version of this patch, please post it. That way we
can better evaluate converting it to use Avro. Thanks!
> Job History log file format is not friendly for external tools.

> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Reporter: Owen O'Malley
> Assignee: Jothi Padmanabhan

> Currently, parsing the job history logs with external tools is very difficult
> because of the format. The most critical problem is that newlines aren't
> escaped in the strings. That makes using tools like grep, sed, and awk very
> tricky.
