Subject [jira] Commented: (HADOOP-1952) Streaming does not handle invalid -inputformat (typo by users for example)

lohit vijayarenu commented on HADOOP-1952:
------------------------------------------

Thanks for looking into this Arun.
The use case here was when a user specifies a partition/combiner class and if we discover
the class is not available, the earlier code used to just ignore it. So, I added the message
to let them know that their specified class does not exists and we are defaulting. Should
I move it to DEBUG and resubmit a patch?

> Hadoop Streaming does not handle invalid inputformat class. For example -inputformat
INVALID class would not be thrown as an error. Instead it defaults to StreamInputFormat. If
an invalid inputformat is specified, it is good to fail.
