Sharad Agarwal commented on MAPREDUCE-157:
------------------------------------------

oops. Realized HistoryEvent is an interface, not an abstract class. Pl ignore my last comment
about making getEventType as public.

> 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.
