Reports of 100% due to rounding should get explicitly stuck at 99.99% until the job is complete. The current system gets things stuck at 100%, which is simply wrong. Even when the true % complete rounds to 100, 100% is still not appropriate to report in the form of a percentage due to the semantics of percentages. This bug occurs frequently when a small number of nodes from a task with many nodes are running very slowly (i.e., the "one overloaded reducer" problem). -- This message is automatically generated by JIRA.
