> when job is in-progress which is having more tasks,one node became unstable due to some
OS issue.After the node became unstable, the map on this node status changed to KILLED state.

> Currently maps which were running on unstable node are rescheduled, and all are in scheduled
state and wait for RM assign container.Seen ask requests for map till Node is good (all those
failed), there are no ask request after this. But AM keeps on preempting the reducers (it's
recycling).
> Finally reducers are waiting for complete mappers and mappers did n't get container..
> My Question Is:
> ============
> why map requests did not sent AM ,once after node recovery.?
