[jira] [Commented] (MAPREDUCE-2606) IsolationRunner broken

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2606?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13061616#comment-13061616 ] 

Eli Collins commented on MAPREDUCE-2606:
----------------------------------------

Yea, looks like IsolationRunner has bit rot for a long time. Given no one uses it and we have MAPREDUCE-2637 for an MR2 replacement I think we can remove it.

> 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)?
