Amar Kamat commented on MAPREDUCE-2806:
---------------------------------------

This is a corner case and can be seen when the task finishes too soon. Thanks Vinay for reporting
this.

> When the Load job's tasks are emulating cpu/memory, the task-tracker kills the emulating
task due to lack of status updates. Load job has its own status reporter which dies too soon.
