Dick King updated MAPREDUCE-986:
--------------------------------
Attachment: MAPREDUCE-986--2009-09-15--1518.patch
This patch caluses a task to not appear in a job trace if we don't know what
its type is.
Also, under the old code, if the task creation line is present but the finish
line is truncated, the taskType becomes null. This will cause the task to be
marked with its type if that happens.
> rumen makes a task with a null type when one of the task lines is truncated

> Rumen was used to produce a job trace, but the job trace contained a
> LoggedTask that had a null taskType. This appears to happen when a Task line
> is truncated.
> We should not put the LoggedTask in the trace at all when this happens.
