Subject [jira] Commented: (HADOOP-476) Streaming should check for correctness of the task
Date Fri, 08 Dec 2006 09:48:23 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-476?page=comments#action_12456750 ] 
Sanjay Dahiya commented on HADOOP-476:

Yoram: This patch doesnt take care of the fact that mapper and reducer are not shipped along.
There are couple of other open issues which should take care of that - HADOOP-805 and HADOOP-797

> Currently, if anythin is wrong with streaming job, it dies without any explanation.
> Before creating and running actual MapReduce job, Streaming should check if:
> -- the executables (or scripts) for -mapper and -reducer are available and have right
> -- the input fragments exist
