Subject [jira] Commented: (HADOOP-472) Streaming should not crash
Date Thu, 24 Aug 2006 06:48:16 GMT

eric baldeschwieler commented on HADOOP-472:
--------------------------------------------

sounds like checking the reconditions before executing is a good idea.

The result of this could just be clearer exceptions.

The question is, should this happen?  If so, it is not an exception.  If not, it is IMO.
