Amareshwari Sriramadasu commented on HADOOP-5547:
-------------------------------------------------
This should not happen, until there are no other nodes in cluster to run the
task. Did you have other nodes with free slot on your cluster?
> One bad node can cause whole job to fail

> Issue Type: Bug
> Reporter: Nathan Marz

> This happened on the 0.19.2 branch. One of the nodes in our cluster was
> having disk problems and every task run on it was failing. In general the
> node would get blacklisted and jobs would run fine on it. However, for one
> job, the job ran the "Job setup" task on this bad node. When the task failed,
> the task was then retried on the same bad node 3 more times until the job
> failed. Hadoop should be able to handle this situation better.
