> 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)?
