IsolationRunner broken
----------------------
Key: MAPREDUCE-2606
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2606
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Alejandro Abdelnur
IsolationRunner it seems it has been broken for a while, it gives a NPE when
trying to use it.
In addition, it supports only Map tasks; to use it the user must ssh to the
node where the task failed; and unless the job has been configured to keep
local files, the job must be run again.
Because of this, IMO, the current implementation of IsolationRunner is not of
much use.
Any objection to remove it from trunk and if people have the need for such
functionality to open another JIRA to build this functionality supported by the
JobTracker (ie via the UI console)?
