Subject [jira] Commented: (MAPREDUCE-430) Task stuck in cleanup with OutOfMemoryErrors
Date Tue, 25 Aug 2009 17:38:59 GMT

Aaron Kimball commented on MAPREDUCE-430:
-----------------------------------------

Arun,

Can you elaborate on the difference between "user" and "system" errors? I can imagine IOException
getting thrown from within Hadoop internals just as much as from within a user's map() method.
The distinction you mentioned above seems somewhat arbitrary to me at first glance.
