TaskTracker number of failed disks to tolerate should be configurable
---------------------------------------------------------------------

                 Key: MAPREDUCE-2924
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2924
             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.
