Michael Bieniosek updated HADOOP-2572:
--------------------------------------
Attachment: hadoop-2572.patch
Here is a patch that ignores FileNotFoundExceptions, and just creates empty
boxes for portions of the output log that are not present.
I marked this issue fix for 0.16.0 -- I'm not sure if I missed the cutoff, but
this is a low-impact issue (only affects the TaskLogServlet), and it makes it
less convenient for me to debug failed map tasks, so it is important for me.
> TaskLogServlet returns 410 when trying to access log early in task life
