[jira] Commented: (HADOOP-673) the task execution environment
should have a current working directory that is task specific
[ http://issues.apache.org/jira/browse/HADOOP-673?page=comments#action_12446770 ]
Mahadev konar commented on HADOOP-673:
--------------------------------------
I do think the suggestion is right-- only that it would involve changes to hadoop-streaming and might break other applications that assume the current working directory to be the directory where the unjarred files lie. That was the only reason I chose the current working directory to be the same for all tasks, but it does seem ugly that all the tasks would share the same workspace. I can make the required changes if people agree on it.

> The tasks should be run in a work directory that is specific to a single task. In particular, I'd suggest using the <local>/jobcache/<jobid>/<taskid> as the current working directory.
