[MAPREDUCE-5255] Reduce task preemption results in task never completing , incomplete fix to MAPREDUCE-3858 ?

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 2.0.3-alpha
• Component/s: mrv2
• Assignee: Unassigned
• Reporter: Rahul Jain
• Created: 17/May/13 20:57

Description

The problem was seen with symptoms very similar to MAPREDUCE-3858: the job is hung with continuous reduce task attempts, each attempt getting killed around commit phase.

After a while the single reduce task was the only one remaining in the job, with 50K 'kills' done for the task.

Relevant logs from application master:
