Sandy Ryza commented on MAPREDUCE-5047:
---------------------------------------
Attempted to make sure that IsolationRunner still works, and it appears to be
broken for other reasons, on both secure and non-secure clusters.
> keep.failed.task.files=true causes job failure on secure clusters

> Project: Hadoop Map/Reduce

> Components: task, tasktracker
> Affects Versions: 1.1.1
> Reporter: Sandy Ryza

> To support IsolationRunner, split info is written to local directories. This
> occurs inside MapTask#localizeConfiguration, which is called both tasktracker
> and by the child JVM. On a secure cluster, the tasktacker's attempt to write
> it fails, because the tasktracker does not have permission to write to the
> user's directory. It is likely that the call to localizeConfiguration in the
> tasktracker can be removed.
