Subject [jira] Commented: (HADOOP-1172) Reduce job failed due to error in logging
Date Fri, 30 Mar 2007 22:29:25 GMT

Owen O'Malley commented on HADOOP-1172:
---------------------------------------

-1

This is not logging from the framework. This is user data and if we lose user data due to
resource constraints, it is appropriate to have the task die.

time, the mapper was actually complete.
