Subject [jira] Commented: (HADOOP-472) Streaming should not crash
Date Tue, 22 Aug 2006 18:27:14 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-472?page=comments#action_12429777 ] 
            
Doug Cutting commented on HADOOP-472:
-------------------------------------

Is it the stack trace that bothers you?  If you want just a single message, then we could
replace the stack trace with the exception name and its message.  If you find particular exception
messages confusing, then we should fix things so that a more informative exception is thrown,
rather than try to translate the messages to something more informative.

> Streaming framework should not end with a Java stack dump.
> All the abnormal conditions should be checked and reported.
> Specific conditions that need to be exmplicitly checked by the framework are:
> -- does the input exist?
> -- do the top level executables or scripts for -mapper and exist
> Any other Exceptions should also be cought and explained in an error message.
