Date Wed, 22 Jun 2011 04:15:47 GMT

Alejandro Abdelnur commented on MAPREDUCE-2606:
-----------------------------------------------

I've reverted the patch in my devel environment, run those tests against the trunk and they
still fail. Could it be that they are broken?

> 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)?
