Subject [jira] Commented: (HADOOP-476) Streaming should check for correctness of the task
Date Wed, 29 Nov 2006 15:43:22 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-476?page=comments#action_12454343 ] 
Sanjay Dahiya commented on HADOOP-476:

I have the cli2 implementation in place, there is one issue with cli2 which is holding it
back. Command line arguments with -jobconf and -env get merged in the same properties set
in CLI's parser and after parsing we dont know what property was passed with which trigger.

I have raised on CLI jira CLI-126. I'll submit the patch once i resolve this one.. 

(http://issues.apache.org/jira/browse/CLI-126) in case auto link doesnt work for other projects.

> 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 input fragments exist
