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.
