Owen O'Malley commented on HADOOP-2367:
---------------------------------------
The race condition between the subprocess finishing and the event being sent
out seemed out of scope for this bug, so I created a new one. HADOOP-2375.

> It would be great to get a representative (2 or 3) sample of builtin java
> profiler for a sample of maps and reduces. I'd store the information in the
> userlog directory and make it available in the local file system of the
> submitting application.
