Subject [jira] [Created] (MAPREDUCE-2606) IsolationRunner broken
Date Mon, 20 Jun 2011 22:36:47 GMT
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)?
