Vinod K V commented on HADOOP-5420:
-----------------------------------
- I think TaskController.terminateTask() and TaskController.killTask() are the
better names than the ones the latest patch introduced. We are actually
cleaning up the task process-trees and just not the JVMs.
- Instead of the latest approach w.r.t encountering disk with no pid written,
it would be better for the LinuxTaskController binary to look in all the disks
configured via mapred.local.dir. It would be simpler to understand this way.
