Arun C Murthy commented on MAPREDUCE-2924:
------------------------------------------
We should strive to make this portable across clusters - thus %disks, not
#disks would be better.
> TaskTracker number of failed disks to tolerate should be configurable

> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: tasktracker
> Affects Versions: 0.20.204.0
> Reporter: Eli Collins

> Like HDFS-1161 but for the TT. The user should be able to configure how many
> valid disks are needed for operation. Currently the TT will start and accept
> tasks even if eg only 1 of its 12 disks is working, which leads to poor
> performance of jobs with tasks that use this machine.
